When it comes to choosing the best pick among Red Gemstones gemstones, Anorthite is known to be a popular choice!Physical properties of Anorthite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Anorthite 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. Anorthite cleavage is nothing but the plane across which the crystal splits during cutting. Anorthite cleavage is Perfect [001] good [010] poor [110],and specific gravity of Anorthite is 2.77.
The physical properties of Anorthite, 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 Anorthite is represented by CaAl 2Si 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006).
