When it comes to choosing the best pick among Blue Gemstones gemstones, Prase is known to be a popular choice!Physical properties of Prase include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Prase 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. Prase cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Prase is 2.64-2.69.
The physical properties of Prase, 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 Prase is represented by SiO 2Michael OâDonoghue , Gems, Sixth Edition (2006).
