When it comes to choosing the best pick among Blue Gemstones gemstones, Covellite is known to be a popular choice!Physical properties of Covellite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Covellite 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. Covellite cleavage is nothing but the plane across which the crystal splits during cutting. Covellite cleavage is Perfect on ,and specific gravity of Covellite is 4.6-4.76.
The physical properties of Covellite, 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 Covellite is represented by CuSMichael OâDonoghue , Gems, Sixth edition (2006) More from other references.
