When it comes to choosing the best pick among Yellow Gemstones gemstones, Marcasite is known to be a popular choice!Physical properties of Marcasite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Marcasite 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. Marcasite cleavage is nothing but the plane across which the crystal splits during cutting. Marcasite cleavage is Indistinct,and specific gravity of Marcasite is 4.80-4.90.
The physical properties of Marcasite, 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 Marcasite is represented by FeS 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
