Ekanite and Tantalite Specific Gravity

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