Hercynite and Moldavite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Hercynite and Moldavite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Hercynite and Moldavite Optical Properties during the identification of gemstone. Specific gravity of Hercynite is 2.32-2.38 whereas that of Moldavite is 2.32-2.38.
