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