Gemstones are identified by gemologists
Gemstones are identified by gemologists. The first characteristic a gemologist uses to identify a gemstone is its chemical composition. Gems are characterized in terms of refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and luster. They may exhibit pleochroism or double refraction. Who describe gems and their characteristics using technical terminology specific to the field of gemology.
Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. They may have luminescence and a distinctive absorption spectrum. For example, diamonds are made of carbon (C) and rubies of aluminium oxide (Al2O3). Another term used is habit, the form the gem is usually found in. For example diamonds, which have a cubic crystal system, are often found as octahedrons.
How to care Gemstone?
To remove any detergent, rinse the stone in the same temperature water as the soaking solution. This type of stone can be strung on silk or nylon thread, the silk being a better choice because it fails to accumulate as much dirt as nylon. For diamonds, sapphires, and rubies, bring an equal mixture of household cleaner and water to a boil.
Opals contain almost one-third water and are therefore particularly vulnerable to even moderate temperature changes. Remove from heat and allow the gemstones to soak in the solution until it cools. Thermal shock happens when a stone is instantly transported from one extreme temperature to another. They are all nature's gifts to us.
