Dravite and Anyolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Anyolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Anyolite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 3.20-3.50 whereas that of Anyolite is 3.20-3.50.
