Serpentine and Anhydrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Serpentine and Anhydrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Serpentine and Anhydrite Optical Properties during the identification of gemstone. Specific gravity of Serpentine is 2.90-2.98 whereas that of Anhydrite is 2.90-2.98.
