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