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