Dravite and Glass Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Glass Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Glass Optical Properties during the identification of gemstone. Specific gravity of Dravite is 2.39-4.00 whereas that of Glass is 2.39-4.00.
