Amazonite and Staurolite Chemical Formula
While comparing Amazonite 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 Amazonite and Staurolite chemical formula.
- Chemical formula of Amazonite- KAlSi3O8
- Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.
Amazonite and Staurolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Amazonite and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Amazonite and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Amazonite is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
