When it comes to choosing the best pick among Gems Found In Africa gemstones, Painite is known to be a popular choice!Physical properties of Painite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Painite 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. Painite cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Painite is 4.00-4.03.
The physical properties of Painite, 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 Painite is represented by CaZrBAl 9O 18Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
