Neptunite and Diamond Specific Gravity

Another important criteria for qualitative analysis of gemstones is Neptunite and Diamond Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Neptunite and Diamond Optical Properties during the identification of gemstone. Specific gravity of Neptunite is 3.50-3.53 whereas that of Diamond is 3.50-3.53.
