Gedrite and Bornite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gedrite and Bornite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gedrite and Bornite Optical Properties during the identification of gemstone. Specific gravity of Gedrite is 5.06-5.08 whereas that of Bornite is 5.06-5.08.
