Schorl Cleavage

When it comes to choosing the best pick among Black Gemstones gemstones, Schorl is known to be a popular choice!Physical properties of Schorl include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Schorl 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. Schorl cleavage is nothing but the plane across which the crystal splits during cutting. .

The physical properties of Schorl, 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.
