Vesuvianite and Afghanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Vesuvianite and Afghanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vesuvianite and Afghanite Optical Properties during the identification of gemstone. Specific gravity of Vesuvianite is 2.55-2.65 whereas that of Afghanite is 2.55-2.65.
