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