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