Turquoise and Hibschite Chemical Formula
While comparing Turquoise and Hibschite 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 Turquoise and Hibschite chemical formula.
- Chemical formula of Turquoise- CuAl6(PO4)4(OH)8 • 4H2O
- Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)
Turquoise and Hibschite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Turquoise and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Turquoise and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Turquoise is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
