Orthoclase and Gahnite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Gahnite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Gahnite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 4.00-4.62 whereas that of Gahnite is 4.00-4.62.
