Charoite and Hydrophane Specific Gravity

Another important criteria for qualitative analysis of gemstones is Charoite and Hydrophane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Charoite and Hydrophane Optical Properties during the identification of gemstone. Specific gravity of Charoite is 1.98-2.50 whereas that of Hydrophane is 1.98-2.50.
