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