Orthoclase and Marialite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Marialite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Marialite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2.50 whereas that of Marialite is 2.50.
