Goshenite and Staurolite Chemical Formula
While comparing Goshenite 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 Goshenite and Staurolite chemical formula.
- Chemical formula of Goshenite- Be3Al2SiO6
- Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.
Goshenite and Staurolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Goshenite and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Goshenite and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Goshenite is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
