Viridine and Almandine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Viridine and Almandine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Viridine and Almandine Optical Properties during the identification of gemstone. Specific gravity of Viridine is 3.95-4.30 whereas that of Almandine is 3.95-4.30.
