Mellite and Nepheline Specific Gravity
Another important criteria for qualitative analysis of gemstones is Mellite and Nepheline Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Mellite and Nepheline Optical Properties during the identification of gemstone. Specific gravity of Mellite is 2.55-2.65 whereas that of Nepheline is 2.55-2.65.
