Papagoite and Lazurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Papagoite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Papagoite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Papagoite is 2.75 whereas that of Lazurite is 2.75.
