When it comes to choosing the best pick among Red Gemstones gemstones, Friedelite is known to be a popular choice!Physical properties of Friedelite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Friedelite 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. Friedelite cleavage is nothing but the plane across which the crystal splits during cutting. Friedelite cleavage is Perfect,and specific gravity of Friedelite is 3.06-3.19.
The physical properties of Friedelite, 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 Friedelite is represented by Mn 8Si 6O 15(OH,Cl) 10Ulrich Henn and Claudio C..
