Gypsum and Serpentine Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gypsum and Serpentine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gypsum and Serpentine Optical Properties during the identification of gemstone. Specific gravity of Gypsum is 2.44-2.62 whereas that of Serpentine is 2.44-2.62.
