Top 3 Precious Gemstones Fundamentals and their Composition

The bounty of nature is not confined to water, light, and air. Nature has also offered us a variety of precious gemstones and minerals that worth a lot. These gemstones are made by individual elements or simple molecules in repeating sheets, chains, or 3D arrangements. These molecules are sorted differently in different kinds of gems, which govern the stone characteristics. The information about gemstones can be done considering the structure of molecules.

Usually, minerals are made when magma or molten rock separates or cools when cold water is sprinkled. Generally, the particles of minerals are small due to their formation in limited areas such as between the grains of sediments or lava flow.

Common minerals present in most of the gemstones are granite, marble, iron, tin, and gold. The most common minerals are silicates, in addition to halides, carbonates, sulfates, sulfides, oxides, and other major classes of minerals.

Besides, minerals make stunning crystals, and highly prized among all are gemstones. It is essential to mention here that the uncut gems are similar to rocks. When they are cut, they get clarity and brilliance.

Precious Gemstones and Their Composition

Remarkably, the gemstones are divided into two groups, precious and semi-precious. It depends on the method of how the minerals are thickened to make the gemstones or how plentiful they are.


Diamonds are formed of carbon atoms, and they are regarded as the most rigid material present on earth. Actually, the diamond cutters are best for cutting glass. They are present in different places on the planet and are made under high pressure and temperature. See also our in-depth article about diamonds here.


They are made by beryl, a mineral having a chemical formula with a mixture of silicon, aluminium, beryllium, and oxygen. If more traces of Vanadium and Chromium are added, the gemstone gets the color it offers. Multiple trace elements can lead to different colors, permitting beryl to make semi-precious stones such as aquamarine.


Ruby is among the precious gemstones, made of a mineral known as Corundum, which contains aluminium oxide. Its red shade is due to Chromium dashes present in it. Besides, Corundum makes sapphires in different colors which is because of the presence of trace elements of chromium, titanium, and iron or their mixture.

Other precious gemstones and their minerals can be Turquoise for turquoise, Topazz for topaz, Opal for opal, Lazurite for Lapis Lazuli, Jadeite for Jade, Grossular for Hessonite, Amber for amber, Almandine-Pyrope Garnet for Rhodolite, Almandine for Garnet, and Albite for moonstone.

Some Factors About Gemstones

Magnetism, density, color, luster, and hardness are the factors that classify precious gemstones and minerals. They are also categorized according to the streak type they leave with the help of a streak tool or how they break.
