Connecting with Natural Stone

|

Andreas and Naomi Kunert, co-founders of Ancient Art of Stone, know they don’t easily fit into one category. Together they create one-of-a-kind art installations using natural stone, crystals, and bronze. 

“We’re not stonemasons, we’re not necessarily sculptors, and we’re not mosaicists. Yet we use all of their skill sets,” Andreas says. 

Andreas and Naomi are artists, first and foremost. It’s not unusual for their art pieces to be 25’ tall. An upcoming project will include a 900-foot mosaic wall, with 20 feet surrounding it and large doorways with 350 ton standing stones that one can walk through. 

“From a megalithic point of view, it’s very moving and very to the point,” Andreas adds. 

Listening to clients and to the stone

Their clients don’t always know what they’re looking for at first. While this approach can be challenging for some people, for artists like Naomi and Andreas, it’s an opportunity to develop a design that is 100% personalized for their clients.

Their most recent client approached them to design a piece to add to their home, which was on 40 acres of land. They were referred by their landscape architect to create a focal point at a roundabout leading up to their home down the long driveway. When they first met with the client, it was clear the client didn’t have a design in mind. In fact, the client had no idea what to suggest; no idea of height, scale, or colors. So Naomi and Andreas came back to their studio and leaned into their process by channeling who they met and hearing what was shared.

“What did they tell us about their life? What was important to them?” Naomi asks. 

The discussion moved from what they felt to what might be important. Family and community seemed important. What Andreas noticed from their initial meeting was the couple was the nucleus of a larger family and they cared about the people in their community. 

“We developed this design of a taller stone standing together, which represents them, husband and wife, and then a sphere, emerging from the two stones, which represents this family and this caring community,” Andreas says.  

When presented with the design, the client loved it without any edits. 

Choosing the right stones

Years of experience have taught Naomi and Andreas what’s possible and working with talented engineers has allowed them to create award-worthy projects for their residential and commercial clients. 

The design is one part of the equation. Another is finding the right stones for each project. Those stones come from a variety of places. While they source some stones in their travels, some come directly from the client. In one instance, Naomi recalls a client whose father collected arrowheads that he found on his land. Those pieces were incorporated into a fireplace design as a way to honor their father. Those types of scenarios aren’t uncommon. 

“I think it does depend also on the client, and what their needs are as part of that listening and as part of my interest in health and healing,” Naomi says. “So through that, listening and getting to know them, there are certain stones that will kind of come more forward in my mind.”

Finding connections

Connections to the ancient art of natural stone used in projects are important to Andreas and Naomi. When it comes to the philosophy of their work, Naomi says it’s wise to look at the ancient ways natural stone has been part of all of creation. For Andreas, whatever they build, they build it with longevity in mind and what they create will outlast our generation and generations to come. 

Commissioned designs are completed in their studio in Cowichan Valley on Vancouver Island and then shipped to the client’s location. It’s not uncommon for a client to become emotionally moved once they see a piece in real life. That’s when Naomi knows the spirit of the stone is speaking to them. Once they’re in front of the artwork, and allow the piece to speak to them, it moves them in a way that cannot be explained.

One project, two minds

Clients love getting the opportunity to work with both Andreas and Naomi. “I think that’s very unique to us, working together as a couple,” Andreas says. “Naomi has an amazing ability to tune into people. When we meet a new client, she can really zero in on who they are and ask them things that stop them in their tracks, makes them think. And ultimately, when the artwork is produced, and it happens every time, they’re very moved; that this is very specific to them. And this pretty much Naomi initially tuning into them. And it is the two of us, that’s really important.”

Understanding Environmental and Health Product Labels for Natural Stone https://usenaturalstone.org/understanding-environmental-and-health-product-labels-for-natural-stone/ Mon, 15 May 2023 18:05:27 +0000 https://usenaturalstone.org/?p=10997 Natural stone has a great reputation for environmentally friendly qualities such as its durability, low embodied energy, no volatile organic compounds (VOCs), and being a nearly complete material in its natural state. Mother Nature does most of the work, making natural stone a single ingredient material suitable for many interior and exterior applications that perform impeccably over time. Most other building materials require additional ingredients and a more complex manufacturing process. Because these added materials and processes can have a negative impact on our health and the environment, they should be considered when selecting a material for a project.

Understanding Environmental and Health Product Labels for Natural Stone

|

The Importance of Material Transparency

Natural stone has a great reputation for environmentally friendly qualities such as its durability, low embodied energy, no volatile organic compounds (VOCs), and being a nearly complete material in its natural state. Mother Nature does most of the work, making natural stone a single ingredient material suitable for many interior and exterior applications that perform impeccably over time. Most other building materials require additional ingredients and a more complex manufacturing process. Because these added materials and processes can have a negative impact on our health and the environment, they should be considered when selecting a material for a project. 

The different manufacturing processes and impacts of building materials are being documented in product labels including Environmental Product Declarations (EPDs) and Health Product Declarations (HPDs). These labels are intended to demonstrate that the health and environmental claims are transparent, accurate, and meet defined standards. These labels can then be used to select and specify building products like natural stone to ensure the well-being of a project’s occupants and the planet. 

Natural stone flooring options are limitless and can also support a healthy interior environment.

“Natural” and “environmentally sustainable” do not mean the same thing. These product labels are significant for the stone industry. They provide independent data to show how using natural stone in projects can support lower embodied carbon goals, providing specifiers with the information needed to make more effective material decisions. These labels also reinforce the important work the natural stone industry has been doing for many years to improve the processes of quarrying, fabricating, transporting, and installing natural stone, which are assessed through the Natural Stone Sustainability Standard.

Impacts during the life cyle of natural stone including raw material acquisition, transportation, manufacturing, use, and end of life are documented in EPDs and HPDs

EPDs and HPDs for Natural Stone Explained

EPDs and HPDs were developed in response to the growing green building movement and requirements that a product’s life cycle impacts are defined and transparent. Just like nutrition labels make it easy to compare ingredients, calories, preservatives, and other information about food products, EPDs and HPDs simplify the process of comparing building materials. The labels themselves do not necessarily tell you if a product is more environmentally friendly than another on their own—rather, they allow you to compare materials using the information provided in the labels to get a more complete understanding of their sustainability claims. To understand this better, let’s discuss these labels in more detail and consider how to use them in your next building or remodeling project.

EPDs

An EPD is a registered document that quantifies environmental information on the life cycle of a product to enable comparisons between products fulfilling the same function. EPDs define the environmental impacts throughout the product’s life cycle. Impacts that are recorded and provided in an EPD include: a product’s global warming potential, eutrophication, acidification, ozone layer depletion, whether the product contains carcinogens, and many others. An EPD may be used for many different applications, including green building design. For example, within LEED, BREEAM, and other green building rating systems, EPDs are used to encourage the purchasing of low carbon products with life-cycle information. Industry-wide natural stone EPDs are available for cladding, flooring/paving, and countertops, making it possible to meet health and environmental goals for any type of project with ease. The natural stone EPDs consider impacts that occur during the quarrying, fabrication, installation, care and maintenance, and disposal of the stone.

Natural stone countertops can play an important role in the health and well-being of an interior and its occupants.

HPDs

HPDs offer greater transparency of material ingredients and their potential human health impacts.  HPDs provide a full disclosure of the potential chemicals of concern in products by comparing product ingredients to a wide variety of “hazard” lists published by government authorities and scientific associations. The HPD should provide 100% disclosure of known ingredients and/or 100% disclosure of known hazards down to 1,000 ppm. All versions of the HPD are recognized within LEED v4 Material Ingredient credits. Within the LEED v4.1 Materials and Resources credit: Building Product Disclosure and Optimization: Material Ingredients, HPDs can also contribute to earning points. Through a special exception for geological materials, HPDs representing dimension stone materials worldwide were developed by the Natural Stone Institute. The HPDs are for common natural stone types used in the dimension stone industry including granite, limestone, marble, quartzite, onyx, sandstone, slate, travertine, and more. There are now 13 HPDs for natural stone that can be found in 15 different MasterFormat classifications, a trusted source for designers. Companies and design teams throughout the industry can take advantage of these industry-wide disclosures.

Stacks and slabs of natural stone ready for use as paving, flooring, or countertops.

Natural Stone Versus Other Materials* 

Let’s compare natural stone to a few other building materials to understand how stone stacks up within these product labels. For example, natural stone countertops were determined to have a global warming potential (GWP) of 46.8kg of CO2e/m2 (weight of carbon dioxide equivalent emitted per square meter) versus engineered quartz, which has a GWP of 102.6kg of CO2e/m2. The EPD demonstrates that natural stone can result in a 54% reduction of embodied carbon.

If you are considering natural stone for the exterior of a project, knowing that its GWP is only 21.4kg of CO2e/m2, versus precast concrete cladding which has a GWP of 62.3kg of CO2e/m2, makes the decision much easier. Choosing natural stone means that your project can have up to 66% less of an impact on the Earth.

While terrazzo is a popular flooring material, it has been shown to have a GWP of 82.2kg of CO2e/m2 versus natural stone which has only 22kg of CO2e/m2. Using natural stone for this same application can support a 37% embodied carbon reduction.

The HPD for marble demonstrates that only marble is present in the material. If you compare that to an HPD for a wood laminate, there are additional ingredients present such as phenol formaldehyde and formaldehyde resin. Exposure to these products is known to irritate the skin, throat, lungs, and eyes. Repeated exposure to formaldehyde can possibly lead to cancer 

Sample HPD material content summary for marble and a wood laminate product.

How to Use EPDs and HPDs

To begin, make it a priority to select materials that will have a measurable positive difference on your health and the environment such as natural stone. Explore the EPD and HPD labels and familiarize yourself with the terms to effectively make comparisons across different materials.  Spend time discussing the various material impacts and options with your designer, material supplier, and installer to optimize the features of the material while also ensuring its long-term use and care. Knowing that you have chosen an environmentally sustainable material will keep you and the planet healthy while also contributing to your peace of mind. 

Natural stone has been used throughout history in iconic structures that symbolize beauty, strength, durability, and permanence. Other materials may strive to mimic these characteristics, but genuine natural materials connect us with the planet and its future in a unique and undeniable way. EPDs and HPDs will only serve to further the thoughtful use of natural stone in environmentally friendly, low carbon building designs for many years to come.

Thassos White Marble Adds Reflection and Beauty to 2 Bryant Park Lobby Project

There aren’t many nearly freestanding buildings in the middle of New York City, but 2 Bryant Park is located on a unique site.

“The building, which is not the tallest building in the area, happens to be open on three sides,” Dan Shannon, architect and managing partner of MdeAS, an architectural company that specializes in commercial office building development, institutional, and multifamily residential developments primarily in the New York City and metropolitan area.

To give some perspective of 2 Bryant Park’s location, it is surrounded by Bryant Park to the south and the Avenue of the Americas on the west.  A public plaza is located on the north side.

The existing building cut the two parks off from one another and had a small, poorly positioned lobby. To better connect these spaces, the central column bay and structural slab were removed from the first and second floor, creating a double-height lobby concourse linking the two parks and pulling pedestrians from one space to the other. 

Shannon and his team wanted to take advantage of the unique footprint of the building and connect the park to the plaza visually. Choosing the right natural stone would prove to be a pivotal decision. They decided to create a two-story high entry lobby passage through the building and elevate that open space using Thassos White marble from Greece along the primary and surrounding walls.

Why Use Natural Stone? 

Shannon is drawn to using natural stone in his projects because natural stone represents quality, durability, tradition, and elegance. He finds we’re also fundamentally moved by natural materials like wood or stone.

“It’s part of our psyche. It’s part of where we came from. It’s part of where we’re going,” Shannon explains. “When people respond in a positive way to an architectural space, it generally has a lot to do with the use of natural materials.”

When he was working on 2 Bryant Park, Shannon was clear in his vision for the spacious lobby and entryway. Those who live, work, and visit New York City are often in a hurry. They need to get from one place to the other and don’t have time to notice the beauty in plain sight. He wanted people who walked into that space to stop—to notice and appreciate the natural stone. He wanted them to respond to it.   

The Different Facets of Thassos White Marble 

Thassos White marble offers different appearances depending on how it’s treated, and that’s one of the reasons he really wanted to use it in 2 Bryant Park.

The predominant walls were made of honed slabs and nylon brushed. “What the nylon brushing did was give it a very nice matte finish,” Shannon explains, “but it also unified the material.”

Shannon reminds us that all natural stone carries some blemishes because it’s a product from nature and not manmade. Through experimentation with their partner in Italy, Roberto Canali from Euromarble, they were able to cover or eliminate some of the blemishes through nylon brushing.

Nylon brushing is also commonly referred to as a leathered finish. “It feels like leather, it’s got a little bit of rippling, but it’s not as rough as thermal,” Shannon adds. “It came into prominence about five to ten years ago and they’re doing it mostly on marbles because it gives the marble a kind of old world look to it. It looks like it’s worn. It gives it a richness.”

Whereas part of the wall features a nearly pure-white sleek matte finish, he and the team wanted contrast for the sides, so they considered black Italian slate.

“Slate has that beautiful cleft finish,” Shannon says. “When it gets pressure along that grain, it cleaves and creates that nice texture cleft surface, which looks like you you’re looking at the topography of the world.”

While the design team and ownership really liked that look, it was decided that the black Italian slate was too much contrast for this room. “We all wanted a more subtle reading.”

This is where the versatility of Thassos White marble came back into play. Shannon went back to Canali to experiment with a different technique on the stone.

“We took large, thick pieces of the Thassos and put them into this hydraulic machine which had a blade on it, which puts pressure along the grain, on top of it, and it shears the marble,” Shannon explains. “What we found was within reason, with a certain size, with a certain amount of pressure, that we could get a positive result in terms of what we were looking for in the appearance.”

The appearance they were going for was that rougher quarry face when you’ve knocked out the blocks.

To achieve the look was the result of a process that involved finding the right size panels that would give them the kind of contours they wanted. “The bigger the panel, the more profile it was, and we couldn’t control it,” he notes. Finding the right size meant they could control the process better by placing the stone panels on wheeled carts so they could move them around. This allowed them to see how they each looked next to each other and get them closer to looking like they naturally belong to each other.

This process also allowed them to work on the panels by hand since some needed handwork to knock down some of the profile. “You may find a perfect piece but it had one bad part,” Shannon says. In that case, someone on Canali’s team would hit it with the chisel and be able to smooth out some of the imperfections or profiles that didn’t work with the adjacent material.

Natural Light Reflections on the Marble 

One of the things Shannon is most proud is how well the natural stone looks on the walls and how the impressive entryway connects to one of New York City’s popular green public spaces.

“It’s kind of like this kaleidoscope connecting these two worlds,” he says. “It really does happen during the day. Sometimes you get the green reflection of the trees that tint the stone because it’s white, and I think that’s just magical. It really is that contrast and the simplicity of it. That is fantastic, you know, just really unique.”


Shannon’s initial vision for the lobby of 2 Bryant Park was for people who walked into that space to stop, to notice and respond to the natural stone. There is no doubt that 2 Bryant Park has carved a name for itself thanks to Shannon and his team who were willing to experiment with what natural stone could do.

Off the Wall: Using Natural Stone to Create a Unique Staircase

|

An earlier version of this article appeared in the Spring 2022 edition of Building Stone Magazine. Photos appear courtesy of PICCO Group.  

A stair project is typically all in a day’s work for an engineer, but what PICCO Group put together for a Toronto homeowner counters logic and the perceived limitations of natural stone.  

The home in question, nestled a few meters down a ravine and surrounded by dense forest in an exclusive neighborhood, was being renovated by Toronto contractor Clemmensen Builders. Sophisticated and modern, the multi-level home with a flat green roof needed a staircase worthy of its simple, elegant geometry.

Clemmensen Builders sought to incorporate stone into the feature stair that would run from the lower level to the main kitchen level. The original solution, developed by architect Peter Clewes of architectsAlliance in Toronto, would be stone “plank” treads cantilevered from an adjacent foundation wall. But that would “create more complexity, challenges, and issues by disturbing the existing old wall, which was thick and made of rubble stone,” says Karl Doucas, principal of the structural engineers PICCO Group, called in to work on the project.

With the intent to fit the home’s contemporary style, Clewes designed the first iteration of the stair with a zig-zag profile. “We wanted to 100 percent respect that design intent but alleviate the structural approach they’d been considering. We envisioned a post-tension stair where the tensioning would be done after the installation. It would be a self-supported stair that wouldn’t rely on the existing structure to support it,” Doucas says. “Although what we proposed was a complicated structure, it would simplify construction and be less disruptive.”

It took a leap of faith on everyone’s part to agree to what eventually would be a five-ton floating stone staircase.

 

Sourcing and Fabricating  

The kitchen, at the top of the soon-to-be showpiece staircase, had basalt flooring. PICCO Group looked locally for stone that would match the kitchen floor but were unsuccessful. Generally,” Doucas says, “with flooring tile it’s slab or tile material. The stair is cubic material. Although the source may be the same, the procurement process is different.”

Doucas attended a building show while sourcing the basalt, where he met Chinese suppliers who might have what he was looking for. “Basalt is a common material in China but comes from only a few quarries that are under government control,” he says. Doucas decided to go directly to the source in China and began making phone calls to find a quarry/fabricator that could secure enough of the specific material, black basalt G684. He landed on Gonmar Trading Company in Xiamen, China.

“They walked us through the procurement process. We provided detailing of the stair and the quantities we needed as well as shop drawings, which they reviewed carefully,” Doucas says. While Gonmar committed to the project, Doucas admits he was still nervous. “Saying and doing are two different things.” After the initial mock-up and review of the first few treads, Doucas says PICCO Group was more comfortable with their choice. Then, the company air freighted material samples to PICCO Group’s Concord, ON office for inspection and material acceptance before work began. During the process there were a lot of virtual meetings and calls.

Aside from matching the kitchen flooring, PICCO Group also chose basalt because of its strength and quality, Doucas says. “In a staircase like this so much stress goes into the material. We needed to make sure the material would be appropriate for the function. But there are tradeoffs. Being a strong material makes it more difficult to fabricate. You need the right fabricator to do this.” Gonmar sent “small but specifically dimensioned stone to conduct ASTM tests domestically.”

Gonmar quarried the blocks from its own mountain quarries in Fujian and processed and cut them to the size needed. They flamed the basalt, heating the stone to a high temperature with a torch then quickly cooling it with water. Small bits of stone pop off the surface, giving it a jagged edge. Then they wire brush it to wear down the sharp edges. The stone has a subtle rough dimpled surface and is naturally non-slip.

The stones needed to be keyed, stepped, and notched to fit into each other. Each step also had to have three holes through which tension cables would run. The holes had to line up perfectly. “That was a key consideration,” Doucas says. “Would the fabricator have the capability of cutting the stone to our specific requirements and be able to do the coring?” Because the stones would be connected along a tension wire as if they were giant beads on a string, “even subtle misalignment of these holes would have presented risks of cable kinks and increased cable stresses.”   

PICCO Group worked closely with Gonmar via telephone, virtual meetings, and video exchanges in addition to quality control reviews by PICCO’s sourcing representative in the region to do dry laying and stone mock-ups. “The precision of drilled holes within tight tolerances through consecutive treads proved more difficult than we expected,” Doucas admits, but in the end, quality control at the Chinese factory showed fabrication and craftsmanship created near-perfect hole alignment.  

Once this almost nine-month process was complete, the stairs traveled for six weeks by boat to Vancouver and then by truck to Toronto.

Assembly Required  

Five pallets of stone were delivered to the site. Small booms craned the stones from the trucks to the pool deck on the home’s kitchen level. Master masons Precision Stone, from Westbury, New York, were tasked with erecting the staircase to exact specifications. Masons wrapped the heavy stones in chain falls (hoists) and dollied them into the house.  

At the top and bottom of the staircase, masons installed robust and heavy stainless-steel plates. On the bottom level, the plate serves as a stop to all the weight and load of the stair above it and was anchored with 12 bolts to an existing lower-level concrete slab that required the addition of a reinforced stair foundation pad.

They then set up a wood “crib” of scaffolding to mimic the final design and used a pulley system to lower each basalt step into place. Masons placed each block of basalt stair in its appropriate spot on the wood crib. They built the staircase from the bottom level up. 

The 19 steps, each weighing 550 pounds, are made up of ten-inch treads and 6 3/16-inch risers. Each step also has three one-inch holes bored through its middle (to house the tension cable) and one through its side (for the handrail connector).

As each block of basalt stair was set in place, masons fed the three 1/2”-steel tension cables through matching holes in the treads consecutively. Pulling wire became more difficult as each tread was placed upon the one below. It took about four days to erect the treads.

“Once you get to the top, you essentially tie off the bottom with a nut and cut off the excess cable. You pull from the cable at the very top to create the tension,” Doucas says.  

There were still a few critical finishing steps. They pumped Hi-flow, quick curing grout, into each cable chase and then sealed each outlet. The grout took a week to consolidate. Then they could remove the temporary wood crib and grout the joints between riser and tread.

The final critical moment for Doucas came when they piled the steps with CMU blocks to simulate the load. “It’s impressive to see all those blocks on there and the stair is really floating. You stand underneath it and say, ‘I hope this thing holds.’ But we had confidence this would work. Post tension stone has been done for hundreds of years in many applications.”  

Once the stair was complete, they incorporated the glass rail system. “We asked the test lab to further confirm the stone material capacity for the type of railing anchor installation specified,” Doucas says. The masons installed and epoxied a stainless-steel threaded rod into the side of each stone step. The design called for a two-pinned look on every tread. The pin goes from the step through the glass, and a decorative nut finishes it off. “It was important to be precise as the glass guard holes were pre-drilled. We had to make sure the final fit was as you see it.”

There is no hiding the “wow” factor of this staircase. “It just wouldn’t have been as impressive in wood,” Doucas says. Its sheer weight and size convey the difficulty in fabrication and engineering. And, he adds, “If you want to evoke a sense of authenticity and communicate durability and longevity there’s no alternative to natural stone. It’s historical, timeless.”

Range, Sustainability, and Beauty: Why Architect Craig Copeland Uses Natural Stone

|

There is no mistaking natural stone for its range, beauty, and sustainability. These are among the many reasons Craig Copeland, AIA, LEED AP BD+C, an architect, sculptor, industrial designer, and partner at Pelli Clarke & Partners finds himself recommending natural stone to many of his clients. He appreciates the qualities of natural stone, particularly marble and travertine, so much that he created another business, Situcraft, a natural stone carving and design studio in New York so he could design furniture made primarily using these types of stone.

 

Maximizing stone’s natural features

“I like natural stone because of the connections to nature and to the earth,” Copeland explains. Unlike other raw material also sourced from the earth, natural stone in its raw state is not only beautiful in its own right, he adds, but he can work with it directly as it is. “It also has incredible durability,” he adds. “There are other natural materials, like wood, that you can work with directly, but they don’t have the same kind of durability that stone has.”

In addition to the sustainability aspect of natural stone, Copeland is drawn to the look stone affords. He appreciates the variability of color and patterning or vein movement and the possibilities of enhancing those features with different textures.

 

Deciding how and when to use natural stone

As an architect, when Copeland and his team want to recommend the use of natural stone to a client, they engage the client and stakeholders in the process. It’s more of a question of where and how to use natural stone rather than if they should use it, he notes.

In many cases, he says, the best place to incorporate natural stone in the design is where you’re closest to the building, both visually and tactically. “Where you actually can see and touch the building or the architecture,” he explains. “I think that’s a big part of it – tapping into the power of stone and our connection to the earth through its use architecturally.”

From a sustainability standpoint, durability is an important reason he often recommends stone for projects. Unlike other materials that need to be updated or replaced regularly, natural stone is often the best choice but, also, with technological advances in extraction and application, a client can get even more expressive forms for a project.

“I think the other beauty of stone is that you can use the stone in a variety of sizes and really procure and enhance the resourcefulness,” he notes, especially as it relates to sustainability. This is important to him not only as an architect but as a designer as well. “There’s more consciousness and more possibilities today.” Where sustainability might have been an afterthought or not even considered in the past, today it’s in the forefront as people consider the role of building materials in mitigating climate change.

 

A natural stone vision for projects

When it makes sense, Copeland will suggest stone for projects even when the client hasn’t considered it. “We start by asking, ‘Where is the value?’” Copeland says. “How far can we extend the value of the stone on any given project? As we’re beginning to answer that question, we engage the clients and talk that through.”

In the case of commercial projects, he says the opportunities to incorporate natural stone might be the paving or the base of the facade. He admits he likes to turn things around sometimes to create interesting effects. For one project, Copeland took what traditionally would be a wood wall and had natural stone installed on the wall and floor in the lobby. “The effect was quite stunning,” he says.

 

Working in marble and travertine

His love for stone extends beyond his practice as an architect.

Copeland enjoys working with marble and travertine when designing furniture pieces for Situcraft. For larger pieces, he leans toward travertine. After spending time observing Henry Moore’s work, an English artist known for his semi-abstract monumental bronze sculptures, Copeland felt that travertine could also pull off those contours and curves.

“For the smaller pieces, I like working in marble,” he says. The type of marble he chooses will depend on what he’s designing and sculpting. “I really enjoy working with [Calacatta] Lasa in terms of its hardness,” he explains. “You can really get incredible detail, but it’s very difficult to work with, so it’s challenging.”

Another way he likes to challenge himself is through the use of wet or dry carving techniques. He enjoys working with stones that have larger deposits of quartz, although it might involve more of a wet carving approach. Most of the carving he’s done has been dry and according to Copeland, when travertine is dry, it actually carves incredibly well.

“The trick with the travertine is its strength is very different in different orientations,” he notes. “So it requires a different sensitivity than marble. Marble is a little bit more forgiving in that sense.”
There are many reasons Copeland gravitates toward natural stone for his architecture and furniture projects. One thing he always comes back to is that its beauty and durability as a natural product of the earth cannot be undermined.

On his Situcraft website, he shares: “Situcraft believes that stone helps ground art, design, and architecture to the natural and real world. Natural stone is the only material that is directly available from the earth, with unequalled durability and beautifully unique forms and colors – the tangible essence of over a hundred million years, available to our touch.”
For Copeland, it’s not a matter of if natural stone should be included in a design. It’s how.

Many people are drawn to natural stone because of its artistic qualities and characteristics. ALMA Studio takes it to the next level.

Part art gallery and part studio, ALMA Studio uses pure light projections to uncover, accentuate, and highlight art scenes that are hidden within the natural veining of stone slabs, according to Jay Zelingold, director of ALMA Studio. Their work and vision follow the methodology developed by artist Arin Jéda.

Not having any formal art training has become an asset for Zelingold and Jéda. Zelingold believes not having that training allows them to break the mold and develop their untraditional art. “I like to say that art in its usual form is the expression of an artist’s inspiration,” Zelingold says. “ALMA is the inspiration from nature’s expression.”

Choosing the right stone is a rich and varied process for ALMA Studio. Zelingold shares that depending on the stone, they might be drawn to its veining, colors, or the strength of the material. Each slab has personality.

“It’s not just the veins and colors but also the blends of minerals that add textures and layers to the stones,” Zelingold explains. The process the team goes through to choose stones is one they’ve spent years developing and refining. Zelingold says they are still learning every time they look for and discover new materials.

Finding the Right Natural Stone

Zelingold and Jéda usually rely on a slab yard as the starting point in their search, especially ones that catalogue each slab that comes through their doors. They begin by looking for slabs that are beautiful on a surface level. The next step is to look within the veining for the hidden stories and scenes their work highlights. In order to discover these scenes, Zelingold says they must inspect hundreds of random slabs from each and every angle in the hope that at some point they will strike gold and find a hidden scene. “In order to streamline the process, instead of blindly inspecting every slab we can get our hands on, we first choose varieties with the strong potential of having hidden scenes,” he explains. “Specifically, the stones we look for are complex, with depth, dimension, and energetic movement.”

Once they choose a variety they want to work with, the next step is to request high-resolution photos of each individual slab in the company’s inventory so they can study them on either a large 4k monitor or even virtual reality (VR) goggles, which allow them to rotate and zoom in to inspect the minutia of detail within the stones.

Sometimes the natural stone features a design so vividly, there is not much more that needs to be done to elevate the vision. They once discovered a piece that has a remarkable likeness to Bob Marley in a portrait orientation with an intense expression on his face and with his hands in the perfect attitude as one would have while playing a guitar. “In this event, we don’t need any other expansions to the scene – that’s a diamond in itself!” Zelingold says.

Their hunt for beautiful slabs has led them to begin reaching out to quarries and showrooms, including Antolini and United Granite.

Bringing Natural Stone to Life

While the team works with a many different types of natural stone to create their art, there are some specific ones they’re drawn to.

“Fusion quartzite, Blue Louise granite, and Arabascato Orobico marble are great examples of styles that make us feel like kids in a candy store,” Zelingold adds. 

Like the stones they use and the artwork they create, the types of clients they serve range from individuals to institutions and commercial spaces. In the short time they’ve been selling their art, within the last 12 months they’ve sold to individuals in the United States and Middle East. Recently, they installed a large slab at a new and upscale steakhouse directly on the Jersey shore, and they’re working on several other private works as well as several high-profile public spaces. 

Zelingold and his team are always exploring new ideas and methods such as backlighting onyx and bringing animation into the installations to make them more immersive and multi-sensory.

Not all of their work is large scale. The team also creates smaller pieces with the same process. “Some of the scenes we discover encompass the entirety of the slab, while other scenes only encompass a small portion of the slab,” Zelingold notes. “In such an event, we will cut around the scene so that we are left with just the part of the slab that contains the discovered scene.”

For one piece, a scene of a bird was identified on the upper left corner of a large slab. Rather than use the entire slab, the team cut that scene out of the slab to create the artwork. 

“Our larger, full-scale slabs are a natural fit for a large public display that desires to bring a magnetic dynamic that will transform their space,” he explains. “Our smaller works are a truly profound addition to an elevated private space or collection. The integration of art, technology, and a three-dimensional piece of mother nature are virtually unsurpassed in both the art and design worlds.” Their goal is to continue to develop artwork that appeals to both homeowners as well as institutions that can incorporate larger pieces into their spaces.

Using Natural Stone and the Golden Ratio to Add Functionality and Inspiration

|

Philosophers and artists have long been fascinated by geometric forms and what gives them meaning beyond their shape. In art and nature there are aesthetically pleasing proportions found, as Michelangelo purportedly did, in what’s referred to as sacred geometry, or the golden ratio (1:phi or 1:1.618…). By channeling an innate sense of this proportion, stone artists Andreas and Naomi Kunert can imbue their unique works with movement, depth, and feeling.

Owners and principal artists of Ancient Art of Stone, the Kunerts create what they call “one-of-a-kind stone portals for individuals, businesses, public museums, and art galleries.” At their 15-acre studio in Cowichan Valley, British Columbia, Canada, they first source stones, then design and build artistic and functional fireplaces, stone doors, spas, mosaics, megaliths, and murals and ship and install them across North America.

According to Andreas, “Everything we do is personal — it’s an intimate experience — and built intuitively. We delve in and go down the rabbit hole and become inspired; our work is the product of this experience.”

 

Meeting of the Minds

Andreas credits Vermont for his love of stone. He grew up in a sparsely populated rural area in that state and spent a lot of time on his own outdoors. An artist by nature — he would eventually dabble in painting and photography — he always loved what he could do with stone, “from the minute to the megalithic; it’s very appealing,” he says.

As a younger man, Andreas was an avid extreme skier and discovered a passion for “life’s mysterious flow.” His adventures took him to the mountains of Europe, and wherever he went he photographed the landscape. He was intrigued by the patterns he saw in nature. He moved to Canada and started K2 Stone Quarries on Vancouver Island. The business grew and was successful. In 2009, he met Naomi, who had been on her own journey.

“I had an early fascination with archaeology and the native Cree people,” Naomi says. She grew up on the Saskatchewan prairie in a home located near a stone grotto and a natural spring where people would visit on pilgrimages for healing. “We’d find arrowheads, stone hammers, teepee circles,” she says, which ignited an “interest in the ancient in terms of stone and how people used it.” In 2000, she got an undergraduate degree in fine arts at the University of Saskatchewan and focused on sculpture and extended media, stone being one of them. Faced with cancer in her late 20s, she found solace and healing with the First Nation medicine people. She credits them with helping her develop visionary abilities that still guide her today. By the time she met Andreas, she says, she had already dreamt of him. More than a decade and five children later, they complement each other in spirit and in business.

 

Passion Embedded

The Kunerts’ projects usually take a year or more and begin with individual stones—lots and lots of stones. While clients often offer them stones, the Kunerts also travel around to fill a trailer with stones from gravel pits and glacial moraines, or they’ll select pallets of natural stone from quarries. “The First Nations also gather stone for us. We’re always searching,” Andreas says, adding that the type of stones they prefer are flat and curved, formed by glaciers. “They’re not river stone. A river tumbles stones round: it doesn’t flatten them. But a glacier will cleave them. We often find them wherever a glacier has been and has left stones behind, even in [a place you wouldn’t expect] like Utah.”

The fireplace project known as “Memories Surround Me” was commissioned by a couple in Spokane, Washington, who were about to move to a home they were having built. While the project did begin with stones, it also began with a client wanting to have something that represented love writ large.

“They met as teenagers and have been married 50 years. They love fly fishing. Every time they go fishing, they bring home a pebble or a saucer-shaped stone. The wife joked that [they’d collected so many stones] they could hardly park in the garage anymore,” Andreas says. The husband asked the Kunerts to use the stones to create a fireplace that he could give his wife as a Christmas gift in tribute to their years together.

The Kunerts work hard to know their clients. “Naomi has the ability to tune into a client and who they are and what we should bring to them in stone or crystal,” says Andreas. She sees working with clients as a spiritual journey. “Not necessarily something religious,” she says, “but the nature of the stones and their honoring can bring connection and peace and stability to our clients’ lives. We build with that intention. We’re building a sacred space that’s also functional artwork.”

As the Kunerts spent time with the Spokane clients, they learned about their hobbies like fly fishing and traveling, that they loved their old home’s unique architecture, and that they wanted to include niches on their fireplace to feature pottery and other small artworks. “We channeled the inspiration into three different design options for them,” Naomi says. Although their hand-drawn sketches can sometimes be detailed, the drawing ultimately has to be open ended. “We tell clients that we let each stone speak. You can’t always find an exact stone for the design.”

The Spokane couple brought about 10 percent of the stones to this project, and the Kunerts supplied the rest of the approximately 15 tons of stone used. Once the sketch was approved the heavy work began.

 

 

Built For Legacy

The fireplace eventually would live in a great room that had yet to be built on a home in a residential neighborhood. When completed, it would stand 22 feet tall. The first step was to make a poured-concrete and rebar substructure of about 18 feet that would be strong enough to hold the stone design embedded on it.

The fireplace was built from the bottom up, in two parts that would be connected on site. On the bottom half of the fireplace, the design incorporates two vertical pieces of sandstone, each two feet thick and each weighing one and a half tons, placed on either side of the firebox. These are connected across the top of the firebox by a 40-inch horizontal piece of sandstone, which is topped by a 12-inch layer of intricately placed individual stones and then an organic-edged granite mantle. Once on site they would add a hand-polished basalt hearth at the base.

The sandstone arrived as square blocks. Using a hydraulic chainsaw, ring saw, hammer, and chisel, Andreas carved into the basic shape to create alcoves and nooks. He then bolted the blocks from behind to the concrete substructure.

The top half of the fireplace holds the central inspiration stone to which the thousands of individual smaller stones find their way.

When the stones arrived, the clients’ contribution and others (from quarries in Colorado and British Columbia), the Kunerts organized them by color and hue, shape (flat or curved) and size. “Some were covered in lichen. Some could be used as feature stones; some would create flow,” Naomi says.

The stones were not numbered or laid out. Knowing where to place the stones, which are essentially a cladding, is where the magic happens. “As much as possible, even though we’re sculptors, we try not to alter the stone, and we use its natural form,” Andreas says.

While there’s a sketch to go by, “We try to honor the shape and color of the stone and how it connects to a particular client. We listen to the stone to see how it wants to be honored or incorporated,” Naomi says. “A stone is as much of a living thing as a plant; it has a certain biology and a matrix.”

The Spokane clients had one large round stone that they wanted to use as the central focal point. “The idea was that the design showed their life together leading to this stone,” Andreas says. “The stones would mean nothing to the average person; they would see just a pile of stones. But to us, they have meaning.” Adds Naomi, “We talk about noticing if a stone is missing from a pile of thousands. They become part of you; it’s like an artist knowing if they have all their tools.”

As with every project, while Andreas mortars the stones to the substructure, he says he takes his time and “feels the stones, listens to the stones. Every day you don’t know which stone is next. You go with a feeling and follow that feeling. It’s hard to describe.”

Which brings us back to the golden ratio and sacred geometry. Andreas says that his perception of the world has always been mysterious and remarkable, and that he has an innate ability to see the sacred geometry and recognize this pattern in nature, people, and materials. “As a child, I discovered I could play with stones on the ground and make these patterns. I wasn’t told about sacred geometry and the math behind it until well into my career.”

Working from the bottom up on this fireplace, Andreas placed the stones in curve and swirl patterns with mortar, bolts, or fastening pins depending on the stone’s size. He also incorporated arrowheads, hammerheads, scrapers and other “hidden treasures.” It was a complex dance to match the design to the concept and make the piece still feel natural and unassuming.

Conscious that the final product would flex and stress on a truck bed, Naomi says, “It’s overbuilt. Probably stronger than anything someone might have built in their home.” Within the concrete is a metal substructure of rebar and plates that runs all the way to the top to connect with lifting eyes, or eye bolts, so a crane could hook into and lift it.

Once the structure was completed, the Kunerts had it loaded onto a truck in two parts and driven 450 miles to Spokane, where the next challenge faced them: craning the 30,000-pound artwork into an exclusive residential neighborhood with homes surrounding the client’s newly built but unfinished home in freezing temperatures. “Usually, our clients have major acreage. This was a tight site,” Andreas says.

The house itself sits on a concrete slab. The great room would be built around the fireplace, whose own foundation goes six feet into the ground. Once the fireplace was craned into place, the two parts, bottom and top, were welded together on the back with steel plates.

“The fireplace will be the strongest part of the house,” Andreas says. “The builders ran the beams into the top, so the fireplace is actually holding up the roof.”

The fireplace’s concrete structure is embedded into the wall, along with the firebox. The builders placed drywall against the sides of the fireplace “nice and snug,” Andreas says, with few gaps for the Kunerts to fill in.

 

Letting Go

The clients are thrilled with their fireplace, their amazingly beautiful and unique piece of functional art that captures their love for one another and their lives together. “On the day it was delivered and lifted into place the client’s wife cried, exclaiming her joy,” Andreas says. Now that the home is complete, they describe the commission as the heart of their home and their favorite room to sit in.

For the Kunerts, after a year of living with and working on a project, it’s always difficult to say goodbye. “It’s personal to us. That’s a piece of our life. Everything that happened in our lives during that year is written into that artwork. Each piece becomes a part of us. When the truck leaves, it’s like ‘There go the children.’ We’re happy and proud but we’re hurting.”

When in the research stage of your home improvement project, it does not take long to discover a growing list of building material options, accompanied by an abundance of information and advice for each. There are many factors and considerations when it comes to selecting the right product. While we’re invested in the benefits of natural stone, we’re also committed to providing natural stone resources to further education in the industry. More education helps ease the process of finding the best fit for their style, taste, and budgets, and to suit their individual project needs. Here are five things to know when you decide on using natural stone for your home improvement project, to help ensure product satisfaction and an overall smooth experience.

  1. Start with a trusted natural stone resource. Understanding natural stone and its attributes is a crucial starting point for a successful project and long-term satisfaction with your selections. You can start by researching natural stone from reputable sources, such as the Natural Stone Institute. With more than 2,000 members in over 50 countries worldwide, the Natural Stone Institute is a valuable resource in the building materials industry for natural stone education.
  2. Know your overall goals. Envision the purpose you want your finished space to serve, and your overall goals for your project (for example: more efficient use of space, more appealing design, entertainment). Note the colors and patterns you’re drawn to, as well as the atmosphere you’re trying to create. Sometimes planning means ruling out things you do not want as you narrow down what fits your vision. This will help guide you toward the best products, collections, and options for your project, which takes the guesswork out and leads to a less overwhelming experience.
  3. Choose your pattern. Natural stone has color and texture variations, which can also vary based on the pattern you choose. While this is part of the appeal of the natural look, you want to make sure you’re aware of the full-color range and possibilities ahead of receiving any materials. Looking at photos is helpful to inspire your imagination but take the opportunity to see the natural stone collections you’re considering in person so you can get an idea of how they might vary, what to expect, and how they might fit with your project (as well as blend with existing features). Two great ways to do this are visiting a showroom or receiving sample.
  4. Give yourself enough time. Plan ahead and give yourself enough time to lay out the scope of your project, coordinate with your mason or fabricator’s schedule, and allow for product lead times. Lead times can vary seasonally and as demand changes; they also vary between different natural stone material options. For best results, and a more reliable timeline, be sure to manage expectations and coordinate accordingly.
  5. Ask questions! Your designer, mason, or fabricator can be another excellent resource on natural stone and other building materials, and you’ll want to take full advantage of their expertise, experience, and advice! When discussing and seeing photos of past projects, you can learn from them what makes a project successful, what works and what doesn’t. You’ll also want to get their insight when it comes to how much material you need, which can vary depending on the chosen product.

When using natural stone, or any other building material for that matter, researching, planning, and making the most of available resources will ensure that your project runs as smoothly and successfully as possible, which is great for everyone involved.

Natural Stone versus Manmade Materials for Interiors

Comparing the performance attributes of natural stone with manmade materials

 

Interior Design

Styles may change from season to season, but Mother Nature creates unique designs in natural stone that are historically innovative and always on trend. This is why natural stone remains a timeless and flexible option for many interior applications including countertops and flooring. The variety of natural stone available is also beautiful, durable, and versatile, offering endless possibilities for interiors.

Manmade materials often attempt to emulate or replicate these characteristics and qualities. It is essential to understand how natural stone compares to some of the manmade materials used for the same applications in order to select the most appropriate material. It is also important to know how the material chosen for an interior project will perform under a variety of circumstances, conditions, and uses. At the same time, knowing how the material impacts the environment will ensure that you are choosing the most sustainable material for the application.

Performance Matters

A material’s optimal performance is based on a combination of the attributes of the material itself, how the material is installed, and the conditions to which it is exposed. There are many different issues to consider for interior applications:

  • How will the material react when it is exposed to heat and elevated temperatures? Some materials will scorch, while others may crack if they are heated too rapidly or unevenly.
  • Can the material withstand exposure to chemicals without a visual change or performance degradation? Exposure to acids or alkali, quite common in kitchens, can potentially cause etching.
  • How stain-resistant is the material? It is important that the material does not stain easily and that stains can be removed easily. Materials with lower absorption rates tend to be more stain-resistant. Using a sealer on more porous materials can lower their absorption rate, helping them to perform better and be more stain-resistant.
  • Is the material slip-resistant? Slip-resistance is the level of traction needed for a walking surface to remain safe for those using it. The texture, porosity, surface treatments, and elements including water, dust, and a build-up of cleaning product residue can alter the slip resistance of the material. Slip resistance is impacted by the material’s texture and porosity, as well as any surface treatments used and elements it is exposed to

Performance attributes should be addressed no matter what material you are considering or what type of project you are working on. These factors play an even more important role in sustainability and in the long-term performance of the material. Let’s look at how natural stone compares to some manmade materials from the perspective of these performance objectives.

Interior Applications for Natural Stone versus Manmade Materials

Countertops

The possibilities for countertops using natural stone are quite extensive. Granite, quartzite, marble, and soapstone are among the many options to consider for these hardworking elements in a kitchen or bath. Every natural stone slab connects directly to nature as a piece of Earth’s history. These stones are versatile, meaning they can be cut and finished into different shapes and patterns, and with various finishes, creating a cohesive aesthetic. There are typically more options for edging and surface textures available for natural stone than manmade surfaces. Because most stone is formed in nature through extreme heat and pressure, natural stone is inherently heat resistant. Granite and quartzite are also very durable and scratch resistant. Marble is particularly prized for its beautiful veining, although it may be susceptible to etching. Although soapstone can scratch easily, it can also be easily repaired. Some stones are porous which may cause the material to stain over time. Sealers are recommended for most applications.

In some cases, natural stone may cost more than manmade materials initially—but often, natural stone proves to be the most cost-effective choice due to its durability.  This is especially true because natural stone can also be refinished, repaired, restored, or recycled.  Stone also has a low embodied energy, an important consideration for sustainability requirements. This is because natural stone was created by the Earth and very little energy or additional resources are needed to quarry, fabricate, and finish it.

Manmade materials including engineered quartz, porcelain, sintered surface, acrylic/solid surface and cultured marble are also options for interior countertops.  These materials typically do not need to be sealed. The patterns and colors of manmade materials are usually consistent within the same dye lot. Acrylic/solid surfaces are repairable, but it is often expensive to do so. Most of these materials do not last as long as stone. Porcelain can be more expensive to purchase and is more expensive to fabricate than natural stone. It is also difficult to repair since the patterns are not full bodied. These materials are typically made in thinner formats which also reduces the edge selection options. This results in the edges not having the same texture and pattern as the surface. The synthetic components of engineered quartz can break down when exposed to UV light. Acrylic, engineered quartz, and cultured marble are not heat or UV resistant. Variation between batches of manufactured materials may cause installation or customer service issues.  Most of these materials also have a high embodied energy because they require a wide range of other materials and energy intensive processes to be manufactured.

Flooring

Natural stones including granite, travertine, limestone, marble, and slate are good options for flooring.  Again, one of the main performance aspects of using natural stone in this manner is its incredible durability. Design options abound with more edge treatments, surface texture, and color than most manmade materials. Most textures are slip-resistant and most natural stones are also UV resistant. Natural stone also comes in a variety of thicknesses and is easy to care for once properly protected.  They will also maintain their color and patina nicely over time if maintained properly.  In some cases, natural stone will cost less than porcelain or concrete imitations.

There are a few other issues to consider. Polished finishes may require a topical treatment to increase the slip resistance. Marble, limestone, and travertine can etch when exposed to acidic substances. Stones that have higher absorption rates will need to be sealed. Once again, the low embodied energy of natural stone makes it a great option for meeting sustainability goals. As previously mentioned, natural stone’s long life cycle makes it a very cost-effective choice.

Porcelain, ceramic, concrete, and terrazzo and plastic-based materials such as laminate and vinyl are among the most popular manmade flooring materials. A few of the pros of using these materials include the durability of ceramic and porcelain. Additionally, ceramic, porcelain, and vinyl are easy to care for. There are usage ratings available for specific applications, which helps make it easier to select the right option for the use you are considering. Terrazzo is a creative material because of the custom options available in production. Laminates are generally inexpensive while porcelain is more expensive than ceramic and other popular flooring materials.

There are a number of cons to using these materials. Porcelain is a heavy and unforgiving material, so specialized equipment is needed to cut it. The density of porcelain often requires that sub-floors and supports are strong enough to withstand the extra weight. These issues can also add to the cost of installation.  Most manmade materials are only manufactured in thinner formats and the edges do not have the same texture or pattern as the surface. Their patterns and sizing are limited and they typically cannot be refinished. Porcelain and ceramic are susceptible to chipping and laminates and vinyl can be easily scratched or indented. Laminate and vinyl also require adhesives that off gas, and laminates are not moisture resistant.  There will be variances across color between batches or lots of the materials. Many of the petroleum-based materials contain chemicals that are toxic, including those marked as Red List chemicals. These products also have high embodied energy, which creates a negative impact on the environment.

Natural Stone and Sustainability

Natural stone has demonstrated considerable durability in local and regional environments and applications. In many cases, these have lasted for hundreds of years, even millennia. Most of the manmade materials have not been around long enough to demonstrate that level of performance. The qualities of longevity and durability have proven that natural stone is a great choice for also meeting green building goals. The initial material and installation costs are off-set by the long life expectancy and the low maintenance requirements. Little to no cleaning or chemicals are required to maintain the material and as mentioned, natural stone can also be refinished, repaired, restored, or recycled. Natural stone is 100% natural stone. Engineered quartz, concrete, and porcelain require many different materials including chemicals to be manufactured and many of them are not recyclable.

So, as Oscar Wilde once said: “Imitation is the sincerest form of flattery that mediocrity can pay to greatness.” Choose natural stone and you will be contributing to the long legacy of great, high-performing, sustainable projects in the world.

If you have researched natural thin stone veneer or spent any time on the internet seeking inspiration, you already know one thing: there are more options to personalize your space than you imagined! Natural stone is quarried across the world in a variety of types, color schemes, patterns, and shapes.

With the right planning and approach, the range of choices is beneficial because each pattern has different characteristics. The traits you like the most about a particular stone can be enhanced by the pattern you choose. This article covers five popular patterns: The Mosaic, Strip, and Roughly Square and Rectangle patterns feature the stone face, while the Ledgestone and Ashlar patterns showcase the end grain. Here is a closer look at each.

 

Ashlar

The Ashlar pattern is a combination of approximately 50% rectangular Strip pieces, 25% Ledge pieces, and 25% small squares. The combination of these three patterns provides the mason with the flexibility to create a unique design for each project. In the photo below, Northeast Walls and Patios installed Colonial Tan thin stone veneer in the Ashlar pattern for the new home’s entryway, pillars, and arch siding.

 

Ledgestone Pattern

Ledgestone (otherwise referred to as Ledge) is made up of thin cut pieces of natural stone often used for siding. These end-grain pieces run in size approximately 1”-4” in height and 6”-14” in length. This pattern creates a unique, layered look when used for stone walls or fireplaces, as you can see in the photo below, featuring design and install by Rockport Post and Beam and Larry Luce Masonry, LLC. The smallest pattern of the five in this article, Ledgestone can be used for a wide range of projects, from home siding to step risers.

 

Mosaic Pattern

The Mosaic pattern includes irregular shapes that fit together like a puzzle, allowing you to create your own unique design. The face surface ranges from approximately .25 to 1.25 square feet. Mosaic patterns are a popular choice to give projects a more natural, rustic look. The accent wall below, featuring Connecticut Blend thin stone veneer and the talents of JJ Stone Design and Masonry, is a great example of how a little stone makes a big impact.

 

Roughly Square and Rectangle

Otherwise called Square & Rec, these pieces are roughly 6”x6” and larger, while the rectangle pieces are longer. In contrast to the Mosaic pattern, Square & Rec is used to create a clean and more modern look. Often used for exterior siding, Square & Rec offers a smooth, consistent shape that puts the focus on the color choice and range. The photo below shows a Connecticut project by J. Salvatore & Sons using Square and Rec on the entrance to coordinate with the front of the home.

 

Strip Pattern

Strip is the pattern that most resembles the layout of brick. The face ranges from approximately 5-8” in height and 12-18” in length. Stones are all cut to almost the same size so they fit together to create a smooth, flat surface. The rectangular shape makes the Strip pattern a good fit for projects needing consistent and longer stones. The fireplace below features the talents of Lakeside Masonry using Spruce Mountain strip patterned thin stone veneer.

Even with a wide range of options, there are no bounds for imagination and creativity. Patterns can be mixed and matched. Homeowners often coordinate with their masons and stone dealers to select a truly customized design that fits their individual project. We love seeing the way these projects maximize the impact of natural stone and showcase the talents of the designers and installers!
