Star Sapphire Cleavage
When it comes to choosing the best pick among Blue Gemstones gemstones, Star Sapphire is known to be a popular choice!Physical properties of Star Sapphire include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Star Sapphire 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. Star Sapphire cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Star Sapphire is 3.90-4.05.
The physical properties of Star Sapphire, 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 Star Sapphire is represented by Al 2O 3Ulrich Henn and Claudio C..
