Cacoxenite and Nepheline Specific Gravity

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