- Chemical formula of Bustamite- (Ca,Mn2+ )Si 3O 9Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Chrysoprase and Bustamite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Bustamite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Bustamite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 3.32-3.43 whereas that of Bustamite is 3.32-3.43.
