When it comes to choosing the best pick among Brown Gemstones gemstones, Povondraite is known to be a popular choice!Physical properties of Povondraite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Povondraite 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. Povondraite cleavage is nothing but the plane across which the crystal splits during cutting. Povondraite cleavage is None,and specific gravity of Povondraite is 3.26.
The physical properties of Povondraite, 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 Povondraite is represented by NaFe3+3Fe3+6(BO 3) 3Si 6O 18(O,OH) 4Anthony et al , Handbook of Mineralogy (2001).
