Enstatite and Orthoclase Specific Gravity

Another important criteria for qualitative analysis of gemstones is Enstatite and Orthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Enstatite and Orthoclase Optical Properties during the identification of gemstone. Specific gravity of Enstatite is 2.54-2.61 whereas that of Orthoclase is 2.54-2.61.
