When it comes to choosing the best pick among Brown Gemstones gemstones, Staurolite is known to be a popular choice!Physical properties of Staurolite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Staurolite Optical Properties are responsible for imparting various physical properties to its structure. Knowledge of these properties is equally important to gem-cutters as well as to consumers. Staurolite cleavage is nothing but the plane across which the crystal splits during cutting. Staurolite cleavage is Distinct on ,and specific gravity of Staurolite is 3.7-3.8.
The physical properties of Staurolite, in fact, are imparted by the chemical composition of its individual molecule. The reactivity or inertness of the crystal is solely governed by its chemical structure. Chemical composition of Staurolite is represented by (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C..
