Vlasovite and Faustite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Vlasovite and Faustite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Vlasovite and Faustite Optical Properties during the identification of gemstone. Specific gravity of Vlasovite is 2.9 whereas that of Faustite is 2.9.
