When it comes to choosing the best pick among Black Gemstones gemstones, Hypersthene is known to be a popular choice!Physical properties of Hypersthene include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Hypersthene 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. Hypersthene cleavage is nothing but the plane across which the crystal splits during cutting. Hypersthene cleavage is Perfect, Perfect,and specific gravity of Hypersthene is 3.45-3.55.
The physical properties of Hypersthene, 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 Hypersthene is represented by (Fe,Mg) 2Si 2O 6Ulrich Henn and Claudio C..
