Afghanite and Sinhalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Sinhalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Sinhalite Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 3.46-3.50 whereas that of Sinhalite is 3.46-3.50.
