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