Afghanite and Hypersthene Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Hypersthene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Hypersthene Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 3.45-3.55 whereas that of Hypersthene is 3.45-3.55.
