Leucite and Moldavite Specific Gravity

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