Chrysoprase and Staurolite Chemical Formula
While comparing Chrysoprase and Staurolite 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 Chrysoprase and Staurolite chemical formula.
- Chemical formula of Chrysoprase- SiO2 (with a high level of nickel impurities )
- Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.
Chrysoprase and Staurolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Chrysoprase and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chrysoprase and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Chrysoprase is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
