Anhydrite and Mimetite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Mimetite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Mimetite Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 7.10 whereas that of Mimetite is 7.10.
