Cuprite and Bertrandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cuprite and Bertrandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cuprite and Bertrandite Optical Properties during the identification of gemstone. Specific gravity of Cuprite is 2.59-2.60 whereas that of Bertrandite is 2.59-2.60.
