Augite and Oligoclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Augite and Oligoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite Vs Oligoclase during the identification of gemstone. Specific gravity of Augite is whereas that of Oligoclase is .
