Tanzanite and Anorthoclase Chemical Formula
While comparing Tanzanite and Anorthoclase 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 Anorthoclase chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Anorthoclase- (Na,K)AlSi 3O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Tanzanite and Anorthoclase Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Anorthoclase Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Anorthoclase Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.56-2.62 whereas that of Anorthoclase is 2.56-2.62.
