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