When it comes to choosing the best pick among Green Gemstones gemstones, Demantoid is known to be a popular choice!Physical properties of Demantoid include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Demantoid 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. Demantoid cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Demantoid is 3.77-3.95.
The physical properties of Demantoid, 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 Demantoid is represented by Ca 3Fe 2(SiO 4) 3Ulrich Henn and Claudio C..
