Narsarsukite and Hercynite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Narsarsukite and Hercynite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Narsarsukite and Hercynite Optical Properties during the identification of gemstone. Specific gravity of Narsarsukite is 4.39 whereas that of Hercynite is 4.39.
