- Chemical formula of Bytownite- Ca(70-90%)Na(30-10%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Annabergite and Bytownite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Annabergite and Bytownite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Annabergite and Bytownite Optical Properties during the identification of gemstone. Specific gravity of Annabergite is 2.72-2.75 whereas that of Bytownite is 2.72-2.75.
