Musgravite and Dravite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Musgravite and Dravite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Musgravite and Dravite Optical Properties during the identification of gemstone. Specific gravity of Musgravite is 3.03-3.18 whereas that of Dravite is 3.03-3.18.
