Chalcopyrite and Pezzottaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcopyrite and Pezzottaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcopyrite and Pezzottaite Optical Properties during the identification of gemstone. Specific gravity of Chalcopyrite is 2.90-3.14 whereas that of Pezzottaite is 2.90-3.14.
