Austinite and Anhydrite Specific Gravity

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