Sugilite and Vlasovite Specific Gravity

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