Prase and Tantalite Specific Gravity

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