Pyrophyllite Cleavage
When it comes to choosing the best pick among Blue Gemstones gemstones, Pyrophyllite is known to be a popular choice!Physical properties of Pyrophyllite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Pyrophyllite 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. Pyrophyllite cleavage is nothing but the plane across which the crystal splits during cutting. Pyrophyllite cleavage is Perfect,and specific gravity of Pyrophyllite is 2.65-2.90.
The physical properties of Pyrophyllite, 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 Pyrophyllite is represented by Al 2Si 4O 10(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
