Staurolite and Xonotlite Physical Properties

Staurolite and Xonotlite Chemical Formula

While comparing Staurolite and Xonotlite 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 Staurolite and Xonotlite chemical formula.

• Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.
• Chemical formula of Xonotlite- Ca 6Si 6O 17(OH) 2Michael O’Donoghue , Gems, Sixth Edition (2006)

Staurolite and Xonotlite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Staurolite and Xonotlite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Staurolite and Xonotlite Optical Properties during the identification of gemstone. Specific gravity of Staurolite is 2.71-2.72 whereas that of Xonotlite is 2.71-2.72.
