Nepheline and Carletonite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nepheline and Carletonite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Carletonite Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 2.45 whereas that of Carletonite is 2.45.
