Augite and Bertrandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Augite and Bertrandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Bertrandite Optical Properties during the identification of gemstone. Specific gravity of Augite is 2.59-2.60 whereas that of Bertrandite is 2.59-2.60.
