Dravite and Hiddenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Dravite and Hiddenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Dravite and Hiddenite Optical Properties during the identification of gemstone. Specific gravity of Dravite is 3.15-3.21 whereas that of Hiddenite is 3.15-3.21.
