Anhydrite and Cavansite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Cavansite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Cavansite Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 2.25-2.33 whereas that of Cavansite is 2.25-2.33.
