Covellite and Grossular Specific Gravity
Another important criteria for qualitative analysis of gemstones is Covellite and Grossular Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Covellite and Grossular Optical Properties during the identification of gemstone. Specific gravity of Covellite is 3.55-3.73 whereas that of Grossular is 3.55-3.73.
