Bastnasite and Adamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Bastnasite and Adamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bastnasite and Adamite Optical Properties during the identification of gemstone. Specific gravity of Bastnasite is 4.32-4.48 whereas that of Adamite is 4.32-4.48.
