Afghanite and Cacoxenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Cacoxenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Cacoxenite Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 2.2-2.6 whereas that of Cacoxenite is 2.2-2.6.
