Gypsum and Violane Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gypsum and Violane Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gypsum and Violane Optical Properties during the identification of gemstone. Specific gravity of Gypsum is 3.22-3.40 whereas that of Violane is 3.22-3.40.
