Willemite Cleavage
When it comes to choosing the best pick among Red Gemstones gemstones, Willemite is known to be a popular choice!Physical properties of Willemite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Willemite 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. Willemite cleavage is nothing but the plane across which the crystal splits during cutting. Willemite cleavage is , imperfect,and specific gravity of Willemite is 3.89-4.18.
The physical properties of Willemite, 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 Willemite is represented by Zn 2SiO 4Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
