Narsarsukite and Augelite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Narsarsukite and Augelite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Narsarsukite and Augelite Optical Properties during the identification of gemstone. Specific gravity of Narsarsukite is 2.70-2.75 whereas that of Augelite is 2.70-2.75.
