When it comes to choosing the best pick among Green Gemstones gemstones, Chalcopyrite is known to be a popular choice!Physical properties of Chalcopyrite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Chalcopyrite 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. Chalcopyrite cleavage is nothing but the plane across which the crystal splits during cutting. Chalcopyrite cleavage is Indistinct on ,and specific gravity of Chalcopyrite is 4.1-4.3.
The physical properties of Chalcopyrite, 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 Chalcopyrite is represented by CuFeS 2Anthony et al , Handbook of mineralogy (2001).
