Nepouite and Papagoite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Nepouite and Papagoite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Nepouite and Papagoite Optical Properties during the identification of gemstone. Specific gravity of Nepouite is 3.25 whereas that of Papagoite is 3.25.
