Tanzanite and Jasper Chemical Formula
While comparing Tanzanite and Jasper 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 Jasper chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Jasper- SiO2
Tanzanite and Jasper Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Jasper Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Jasper Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.58-2.91 whereas that of Jasper is 2.58-2.91.
