Ceylonite and Nephrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Ceylonite and Nephrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Ceylonite and Nephrite Optical Properties during the identification of gemstone. Specific gravity of Ceylonite is 2.90-3.10 whereas that of Nephrite is 2.90-3.10.
