Stibiotantalite and Austinite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Austinite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Austinite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 4.12 whereas that of Austinite is 4.12.
