Tanzanite and Xonotlite Chemical Formula
While comparing Tanzanite and Xonotlite 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 Xonotlite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Xonotlite- Ca 6Si 6O 17(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006)
Tanzanite and Xonotlite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Xonotlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Xonotlite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.71-2.72 whereas that of Xonotlite is 2.71-2.72.
