Chalcopyrite and Albite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chalcopyrite and Albite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chalcopyrite and Albite Optical Properties during the identification of gemstone. Specific gravity of Chalcopyrite is 2.60-2.65 whereas that of Albite is 2.60-2.65.
