Tanzanite and Pyrophyllite Chemical Formula
While comparing Tanzanite and Pyrophyllite 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 Pyrophyllite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Pyrophyllite- Al 2Si 4O 10(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references
Tanzanite and Pyrophyllite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Pyrophyllite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Pyrophyllite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.65-2.90 whereas that of Pyrophyllite is 2.65-2.90.
