Cavansite and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cavansite and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cavansite and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Cavansite is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
