Simpsonite and Cobaltite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Simpsonite and Cobaltite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Simpsonite and Cobaltite Optical Properties during the identification of gemstone. Specific gravity of Simpsonite is 6.3 whereas that of Cobaltite is 6.3.
