Stibiotantalite and Euclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Euclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Euclase Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 3.08-3.12 whereas that of Euclase is 3.08-3.12.
