Andalusite and Uvarovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Andalusite and Uvarovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Andalusite and Uvarovite Optical Properties during the identification of gemstone. Specific gravity of Andalusite is 3.77 whereas that of Uvarovite is 3.77.
