Steatite and Anhydrite Specific Gravity

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