Tanzanite and Sanidine Chemical Formula
While comparing Tanzanite and Sanidine 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 Sanidine chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Sanidine- KAlSi 3O 8Michael OâDonoghue , Gems, Sixth Edition (2006)
Tanzanite and Sanidine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Sanidine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Sanidine Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.54-2.61 whereas that of Sanidine is 2.54-2.61.
