Cinnabar and Fayalite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Cinnabar and Fayalite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cinnabar and Fayalite Optical Properties during the identification of gemstone. Specific gravity of Cinnabar is 4.392 whereas that of Fayalite is 4.392.
