Melanite Cleavage
When it comes to choosing the best pick among Black Gemstones gemstones, Melanite is known to be a popular choice!Physical properties of Melanite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Melanite 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. Melanite cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Melanite is 3.70-4.10.
The physical properties of Melanite, 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 Melanite is represented by Ca 3Fe 2(SiO 4) 3Arthur Thomas , Gemstones (2009).
