When it comes to choosing the best pick among Yellow Gemstones gemstones, Boracite is known to be a popular choice!Physical properties of Boracite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Boracite 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. Boracite cleavage is nothing but the plane across which the crystal splits during cutting. Boracite cleavage is None,and specific gravity of Boracite is 2.95-2.96.
The physical properties of Boracite, 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 Boracite is represented by Mg 3B 7O 13ClMichael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
