Demantoid and Sugilite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Demantoid and Sugilite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Demantoid and Sugilite Optical Properties during the identification of gemstone. Specific gravity of Demantoid is 2.69-2.79 whereas that of Sugilite is 2.69-2.79.
