Zincite and Demantoid Specific Gravity
Another important criteria for qualitative analysis of gemstones is Zincite and Demantoid Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Zincite and Demantoid Optical Properties during the identification of gemstone. Specific gravity of Zincite is 3.77-3.95 whereas that of Demantoid is 3.77-3.95.
