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