Goethite Cleavage

When it comes to choosing the best pick among Brown Gemstones gemstones, Goethite is known to be a popular choice!Physical properties of Goethite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Goethite 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. Goethite cleavage is nothing but the plane across which the crystal splits during cutting. Goethite cleavage is Perfect ,and specific gravity of Goethite is 4.27-4.29.

The physical properties of Goethite, 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 Goethite is represented by FeO(OH)Arthur Thomas , Gemstones (2009).
