Bornite and Boleite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Bornite and Boleite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bornite and Boleite Optical Properties during the identification of gemstone. Specific gravity of Bornite is 5.05 whereas that of Boleite is 5.05.
