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