Gahnospinel and Epidote Specific Gravity

Another important criteria for qualitative analysis of gemstones is Gahnospinel and Epidote Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gahnospinel and Epidote Optical Properties during the identification of gemstone. Specific gravity of Gahnospinel is 3.25-3.50 whereas that of Epidote is 3.25-3.50.
