When it comes to choosing the best pick among Brown Gemstones gemstones, Magnetite is known to be a popular choice!Physical properties of Magnetite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Magnetite 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. Magnetite cleavage is nothing but the plane across which the crystal splits during cutting. Magnetite cleavage is None,and specific gravity of Magnetite is 5.2.
The physical properties of Magnetite, 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 Magnetite is represented by Fe 3O 4Ulrich Henn and Claudio C..
