Tantalite and Cryolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Tantalite and Cryolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tantalite and Cryolite Optical Properties during the identification of gemstone. Specific gravity of Tantalite is 2.97 whereas that of Cryolite is 2.97.
