Williamsite and Turquoise Chemical Formula
While comparing Williamsite and Turquoise 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 Williamsite and Turquoise chemical formula.
- Chemical formula of Williamsite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
- Chemical formula of Turquoise- CuAl6(PO4)4(OH)8 • 4H2O
Williamsite and Turquoise Specific Gravity
Another important criteria for qualitative analysis of gemstones is Williamsite and Turquoise Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Williamsite and Turquoise Optical Properties during the identification of gemstone. Specific gravity of Williamsite is 2.30-2.90 whereas that of Turquoise is 2.30-2.90.
