Gypsum and Carnelian Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gypsum and Carnelian Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gypsum and Carnelian Optical Properties during the identification of gemstone. Specific gravity of Gypsum is 2.58-2.64 whereas that of Carnelian is 2.58-2.64.
