Tanzanite and Ametrine Chemical Formula
While comparing Tanzanite and Ametrine 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 Ametrine chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Ametrine- SiO2
Tanzanite and Ametrine Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Ametrine Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Ametrine Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.65 whereas that of Ametrine is 2.65.
