When it comes to choosing the best pick among Semi Precious Gemstones gemstones, Jasper is known to be a popular choice!Physical properties of Jasper include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Jasper 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. Jasper cleavage is nothing but the plane across which the crystal splits during cutting. Jasper cleavage is Indiscernible,and specific gravity of Jasper is 2.58-2.91.
The physical properties of Jasper, 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 Jasper is represented by SiO2.
