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