Tanzanite and Williamsite Chemical Formula
While comparing Tanzanite and Williamsite 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 Williamsite chemical formula.
- Chemical formula of Tanzanite- Ca2Al3(SiO4)3(OH)
- Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
Tanzanite and Williamsite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Tanzanite and Williamsite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Tanzanite and Williamsite Optical Properties during the identification of gemstone. Specific gravity of Tanzanite is 2.51-2.63 whereas that of Williamsite is 2.51-2.63.
