Cinnabar and Simpsonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cinnabar and Simpsonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cinnabar and Simpsonite Optical Properties during the identification of gemstone. Specific gravity of Cinnabar is Not Available whereas that of Simpsonite is Not Available.
