Stibiotantalite and Nifontovite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Nifontovite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Nifontovite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 2.35-2.36 whereas that of Nifontovite is 2.35-2.36.
