When it comes to choosing the best pick among Black Gemstones gemstones, Proustite is known to be a popular choice!Physical properties of Proustite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Proustite 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. Proustite cleavage is nothing but the plane across which the crystal splits during cutting. Proustite cleavage is Distinct on ,and specific gravity of Proustite is 5.51-5.64.
The physical properties of Proustite, 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 Proustite is represented by Ag 3AsS 3Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
