When it comes to choosing the best pick among Brown Gemstones gemstones, Mellite is known to be a popular choice!Physical properties of Mellite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Mellite 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. Mellite cleavage is nothing but the plane across which the crystal splits during cutting. Mellite cleavage is Imperfect,and specific gravity of Mellite is 1.58-1.60.
The physical properties of Mellite, 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 Mellite is represented by Al 2(Cl 2O 12) · 18H 2OUlrich Henn and Claudio C..
