Anhydrite and Baryte Specific Gravity

Another important criteria for qualitative analysis of gemstones is Anhydrite and Baryte Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Anhydrite and Baryte Optical Properties during the identification of gemstone. Specific gravity of Anhydrite is 4.3-5 whereas that of Baryte is 4.3-5.
