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