Tanzanite and Inderite Chemical Formula
While comparing Tanzanite and Inderite 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 Inderite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Inderite- MgB 3O 3(OH) 5 · 5H 2OMichael OâDonoghue , Gems, Sixth Edition (2006)
Tanzanite and Inderite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Inderite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Inderite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 1.79 whereas that of Inderite is 1.79.
