When it comes to choosing the best pick among Yellow Gemstones gemstones, Pyrite is known to be a popular choice!Physical properties of Pyrite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Pyrite 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. Pyrite cleavage is nothing but the plane across which the crystal splits during cutting. Pyrite cleavage is Indistinct on ; partings on and ,and specific gravity of Pyrite is 5.00-5.20.
The physical properties of Pyrite, 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 Pyrite is represented by FeS 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
