What makes gemstones

What makes gemstones so valuable? There are a few things to focus on when finding the value of your gemstones: 1. Durability One of its most important characteristics is its ability to endure. Rarity Wearing a gemstone which very few other people own is exciting. Acceptability Fashion trends and developments also play an important role in determining the value of different gemstones.

Diamonds, emeralds, rubies, and sapphires are all considered to be precious, and thereby, the most valuable and most desirable. All other gemstones are considered semi-precious.

Natural vs. Synthetic Gemstones Natural gemstones are found in nature, created deep in the Earth and mined out of it. They are sometimes enhanced, which means they were treated in some way to improve their color or clarity. This often involves heat or delicate chemical processes. Depending on the type and extent of treatment, they can affect the value of the stone. Synthetic or Lab-created gemstones, on the other hand, are formed in laboratories by human hands and machines.

They are chemical, physical, and optically identical to gems found in nature. Of course, lab-created gemstones don't have the rarity of natural gemstones, which is why they are less valuable. Nowadays, synthetic versions of nearly all popular gemstones are available. Some modern synthetic gemstones look more natural and are more difficult to identify, but an experienced jeweler or gemologist can usually detect them.

Simulant Gemstones Simulant or imitation gemstones can be anything that resembles the natural gemstones but does not have the same physical characteristics or chemical composition. These items are usually much less expensive than natural forms. Simulant stones are often made of glass or plastic, and most can be detected easily by a jeweler. Activation mail sent.

Value is based on rarity and rare quality. As mentioned, gems appear coloured due to some of the white light being absorbed within the minerals structure.

Most gems are coloured by a limited number of metals present either as impurities, as in Allochromatic gems or as essential constituents of the atomic structure, as in Idiochromatic gems. Alongside this, gemstones are rare and made naturally. This means that rubies, emeralds, sapphires, diamonds and so on are created in rocks found in the earth's crust, roughly three to 25 miles beneath the earth's surface. However, diamonds are formed much deeper in the Earth's surface.

The earth's crust is made up of three different kinds of rock; igneous, sedimentary and metamorphic. Each type of rock forms under different circumstances, resulting in the array of different gemstones we see. The cooling and crystallization of magma beneath the earth's surface intrusive or plutonic. Interlinking crystals grow within intrusive igneous rock, sometimes forming gemstones depending on the following three factors;.

If the magma doesn't reach the surface, it cools more slowly, crystallising and forming coarse-grained minerals. Sedimentary Rock is a rock formed by the deposition and successive cementation of the material at the Earth's surface within bodies of water.

Sedimentary gemstone happens when water mixes with minerals on the Earth's surface. Rock is worn down, and fragments of mineral rich water and wind seeps down into the cracks and cavities in the Earth's surface, depositing layers of minerals which are then compressed over time, forming gemstones.
