Wardite and Nepouite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Wardite and Nepouite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Wardite and Nepouite Optical Properties during the identification of gemstone. Specific gravity of Wardite is 3.18-3.24 whereas that of Nepouite is 3.18-3.24.
