Orthoclase and Cinnabar Specific Gravity

Another important criteria for qualitative analysis of gemstones is Orthoclase and Cinnabar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Orthoclase and Cinnabar Optical Properties during the identification of gemstone. Specific gravity of Orthoclase is 2 whereas that of Cinnabar is 2.
