Tanzanite and Aegirine Chemical Formula
While comparing Tanzanite and Aegirine 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 Aegirine chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Aegirine- (Na,Fe,Ca)Si 2O 6Ulrich Henn and Claudio C.
Tanzanite and Aegirine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Aegirine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Aegirine Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 3.50-3.60 whereas that of Aegirine is 3.50-3.60.
