Covellite and Sapphire Specific Gravity
Another important criteria for qualitative analysis of gemstones is Covellite and Sapphire Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Covellite and Sapphire Optical Properties during the identification of gemstone. Specific gravity of Covellite is 3.95-4.03 whereas that of Sapphire is 3.95-4.03.
