Papagoite and Corundum Specific Gravity
Another important criteria for qualitative analysis of gemstones is Papagoite and Corundum Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Papagoite and Corundum Optical Properties during the identification of gemstone. Specific gravity of Papagoite is 3.90-4.05 whereas that of Corundum is 3.90-4.05.
