Afghanite and Aegirine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Afghanite and Aegirine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Afghanite and Aegirine Optical Properties during the identification of gemstone. Specific gravity of Afghanite is 3.50-3.60 whereas that of Aegirine is 3.50-3.60.
