When it comes to choosing the best pick among Gems Found In Australia gemstones, Bytownite is known to be a popular choice!Physical properties of Bytownite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Bytownite 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. Bytownite cleavage is nothing but the plane across which the crystal splits during cutting. Bytownite cleavage is Perfect on [001], good on [010], imperfect on [110],and specific gravity of Bytownite is 2.72-2.75.
The physical properties of Bytownite, 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 Bytownite is represented by Ca(70-90%)Na(30-10%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006).
