Stibiotantalite and Hardystonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Stibiotantalite and Hardystonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Stibiotantalite and Hardystonite Optical Properties during the identification of gemstone. Specific gravity of Stibiotantalite is 3.396-3.443 whereas that of Hardystonite is 3.396-3.443.
