Papagoite and Sellaite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Papagoite and Sellaite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Papagoite and Sellaite Optical Properties during the identification of gemstone. Specific gravity of Papagoite is 3.14-3.16 whereas that of Sellaite is 3.14-3.16.
