When it comes to choosing the best pick among Red Gemstones gemstones, Bustamite is known to be a popular choice!Physical properties of Bustamite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Bustamite 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. Bustamite cleavage is nothing but the plane across which the crystal splits during cutting. Bustamite cleavage is perfect; and good; poor,and specific gravity of Bustamite is 3.32-3.43.
The physical properties of Bustamite, 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 Bustamite is represented by (Ca,Mn2+ )Si 3O 9Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
