Adamite and Vlasovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Adamite and Vlasovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Adamite and Vlasovite Optical Properties during the identification of gemstone. Specific gravity of Adamite is 2.97 whereas that of Vlasovite is 2.97.
