Lazurite and Bastnasite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Lazurite and Bastnasite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Lazurite and Bastnasite Optical Properties during the identification of gemstone. Specific gravity of Lazurite is 4.95-5.0 whereas that of Bastnasite is 4.95-5.0.
