Nephrite and Prase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nephrite and Prase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nephrite and Prase Optical Properties during the identification of gemstone. Specific gravity of Nephrite is 2.64-2.69 whereas that of Prase is 2.64-2.69.
