Tanzanite and Anorthite Chemical Formula
While comparing Tanzanite and Anorthite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Tanzanite and Anorthite chemical formula.

- Chemical formula of Anorthite- CaAl 2Si 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Tanzanite and Anorthite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Anorthite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Anorthite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.77 whereas that of Anorthite is 2.77.
