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