Orthoclase and Gahnospinel Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Gahnospinel Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Gahnospinel Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 3.65-4.55 whereas that of Gahnospinel is 3.65-4.55.
