Cuprite and Hercynite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cuprite and Hercynite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cuprite and Hercynite Optical Properties during the identification of gemstone. Specific gravity of Cuprite is 4.39 whereas that of Hercynite is 4.39.
