Diaspore and Tantalite Specific Gravity

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