Dravite and Uvite Specific Gravity

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