Astrophyllite Cleavage
When it comes to choosing the best pick among Green Gemstones gemstones, Astrophyllite is known to be a popular choice!Physical properties of Astrophyllite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Astrophyllite 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. Astrophyllite cleavage is nothing but the plane across which the crystal splits during cutting. Astrophyllite cleavage is Perfect on [001] imperfect on [100],and specific gravity of Astrophyllite is 3.2-3.4.
The physical properties of Astrophyllite, 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 Astrophyllite is represented by (K,Na) 3(Fe2+ ,Mn) 7Ti 2Si 8O 24(O,OH) 7Anthony et al , Handbook of mineralogy (2001).
