Riebeckite and Gypsum Specific Gravity

Another important criteria for qualitative analysis of gemstones is Riebeckite and Gypsum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Riebeckite and Gypsum Optical Properties during the identification of gemstone. Specific gravity of Riebeckite is 2.20-2.40 whereas that of Gypsum is 2.20-2.40.
