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