Moldavite and Andalusite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Moldavite and Andalusite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Moldavite and Andalusite Optical Properties during the identification of gemstone. Specific gravity of Moldavite is 3.05-3.21 whereas that of Andalusite is 3.05-3.21.
