Stibiotantalite and Corundum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Corundum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Corundum Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 3.90-4.05 whereas that of Corundum is 3.90-4.05.
