Afghanite and Baryte Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Baryte Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Baryte Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 4.3-5 whereas that of Baryte is 4.3-5.
