Uvite and Tantalite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Uvite and Tantalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Uvite and Tantalite Optical Properties during the identification of gemstone. Specific gravity of Uvite is 5.2 whereas that of Tantalite is 5.2.
