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.

Popularity of the Indian Silver Jewellery
It might surprise people to find out that the Elements Class contains minerals that are composed of more than one element. Popularity of the Indian Silver Jewellery is associated with the elegance and versatility of it. The most difficult to classify are the metal/non-metal mineral combinations.
Elements, by the chemical definition are composed of all the same atoms; whereas substances composed of two or more elements are compounds. These minerals, which combine metals such as iron with the very non-metallic elements of carbon, nitrogen, phosphorous and silicon, are quite unique and quite rare. But the sulfides class is by convention limited to sulfur and semi-metal combinations as discussed above. They are not too different from sulfides which typically combine metals with sulfur.
