Enstatite and Nephrite Specific Gravity

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