Anhydrite and Hexagonite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Hexagonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Hexagonite Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 2.98-3.03 whereas that of Hexagonite is 2.98-3.03.
