Cryolite and Staurolite Physical Properties

Cryolite and Staurolite Chemical Formula

While comparing Cryolite 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 Cryolite and Staurolite chemical formula.

• Chemical formula of Cryolite- Na 3AlF 6Ulrich Henn and Claudio C.
• Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.

Cryolite and Staurolite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Cryolite and Staurolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Cryolite and Staurolite Optical Properties during the identification of gemstone. Specific gravity of Cryolite is 3.7-3.8 whereas that of Staurolite is 3.7-3.8.
