Tantalite and Bort Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tantalite and Bort Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tantalite and Bort Optical Properties during the identification of gemstone. Specific gravity of Tantalite is Not Available whereas that of Bort is Not Available.
