Nepheline and Hypersthene Specific Gravity

Another important criteria for qualitative analysis of gemstones is Nepheline and Hypersthene Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepheline and Hypersthene Optical Properties during the identification of gemstone. Specific gravity of Nepheline is 3.45-3.55 whereas that of Hypersthene is 3.45-3.55.
