Orthoclase and Creedite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Orthoclase and Creedite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Creedite Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2.70 whereas that of Creedite is 2.70.
