Sapphirine Cleavage
When it comes to choosing the best pick among Green Gemstones gemstones, Sapphirine is known to be a popular choice!Physical properties of Sapphirine include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Sapphirine 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. Sapphirine cleavage is nothing but the plane across which the crystal splits during cutting. Sapphirine cleavage is Perfect,and specific gravity of Sapphirine is 3.40-3.58.
The physical properties of Sapphirine, 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 Sapphirine is represented by (Al,Mg) 8(Al,Si) 6O 20Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
