Nephrite and Pyrrhotite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nephrite and Pyrrhotite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nephrite and Pyrrhotite Optical Properties during the identification of gemstone. Specific gravity of Nephrite is 4.58-4.65 whereas that of Pyrrhotite is 4.58-4.65.
