When it comes to choosing the best pick among Yellow Gemstones gemstones, Norbergite is known to be a popular choice!Physical properties of Norbergite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Norbergite 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. Norbergite cleavage is nothing but the plane across which the crystal splits during cutting. Norbergite cleavage is Distinct,and specific gravity of Norbergite is 3.177.
The physical properties of Norbergite, 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 Norbergite is represented by Mg 3(SiO 4)(F,OH) 2Anthony et al , Handbook of Mineralogy (2001).
