Bornite and Cuprite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Bornite and Cuprite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bornite and Cuprite Optical Properties during the identification of gemstone. Specific gravity of Bornite is 5.85-6.15 whereas that of Cuprite is 5.85-6.15.
