Afghanite and Quartz Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Quartz Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Quartz Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 2.65 whereas that of Quartz is 2.65.
