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