Zoisite and Charoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zoisite and Charoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zoisite and Charoite Optical Properties during the identification of gemstone. Specific gravity of Zoisite is 2.54-2.78 whereas that of Charoite is 2.54-2.78.
