Chalcopyrite and Pyrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcopyrite and Pyrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcopyrite and Pyrophyllite Optical Properties during the identification of gemstone. Specific gravity of Chalcopyrite is 2.65-2.90 whereas that of Pyrophyllite is 2.65-2.90.
