Jade and Tanzanite Chemical Formula
While comparing Jade and Tanzanite 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 Jade and Tanzanite chemical formula.
- Chemical formula of Jade- Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
Jade and Tanzanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Jade and Tanzanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Jade and Tanzanite Optical Properties during the identification of gemstone. Specific gravity of Jade is 3.35 whereas that of Tanzanite is 3.35.
