  • Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)

Bornite and Augite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Bornite and Augite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bornite and Augite Optical Properties during the identification of gemstone. Specific gravity of Bornite is 3.19-3.56 whereas that of Augite is 3.19-3.56.
