Anhydrite and Galena Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Galena Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Galena Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 6.23 whereas that of Galena is 6.23.
