Moldavite and Nuummite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moldavite and Nuummite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Nuummite Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 3.18-3.37 whereas that of Nuummite is 3.18-3.37.
