Pyrophyllite and Chalcopyrite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Pyrophyllite and Chalcopyrite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Pyrophyllite and Chalcopyrite Optical Properties during the identification of gemstone. Specific gravity of Pyrophyllite is 4.1-4.3 whereas that of Chalcopyrite is 4.1-4.3.
