Gibbsite and Papagoite Specific Gravity

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