Wardite and Neptunite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wardite and Neptunite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wardite and Neptunite Optical Properties during the identification of gemstone. Specific gravity of Wardite is 3.19-3.23 whereas that of Neptunite is 3.19-3.23.
