When it comes to choosing the best pick among gemstones, Faustite is known to be a popular choice!Physical properties of Faustite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Faustite 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. Faustite cleavage is nothing but the plane across which the crystal splits during cutting. Faustite cleavage is Indistinct,and specific gravity of Faustite is 2.9.
The physical properties of Faustite, 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 Faustite is represented by (Zn,Cu)Al 6(PO 4) 4(OH) 8 · 4H 2OMichael OâDonoghue , Gems, Sixth Edition (2006).
