Stibiotantalite and Norbergite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Norbergite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Norbergite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 3.177 whereas that of Norbergite is 3.177.
