When it comes to choosing the best pick among Red Gemstones gemstones, Bornite is known to be a popular choice!Physical properties of Bornite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Bornite 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. Bornite cleavage is nothing but the plane across which the crystal splits during cutting. Bornite cleavage is Poor on [111].,and specific gravity of Bornite is 5.06-5.08.
The physical properties of Bornite, 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 Bornite is represented by Cu5FeS4.
