Covellite and Smithsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Covellite and Smithsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Covellite and Smithsonite Optical Properties during the identification of gemstone. Specific gravity of Covellite is 4.00-4.65 whereas that of Smithsonite is 4.00-4.65.
