Vesuvianite and Gypsum Specific Gravity

Another important criteria for qualitative analysis of gemstones is Vesuvianite and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vesuvianite Vs Gypsum during the identification of gemstone. Specific gravity of Vesuvianite is whereas that of Gypsum is .
