Norbergite and Stibiotantalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Norbergite and Stibiotantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Norbergite and Stibiotantalite Optical Properties during the identification of gemstone. Specific gravity of Norbergite is Not Available whereas that of Stibiotantalite is Not Available.
