When it comes to choosing the best pick among Gems for Taurus gemstones, Carnelian is known to be a popular choice!Physical properties of Carnelian include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Carnelian 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. Carnelian cleavage is nothing but the plane across which the crystal splits during cutting. Carnelian cleavage is Absent,and specific gravity of Carnelian is 2.58-2.64.
The physical properties of Carnelian, 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 Carnelian is represented by SiO2.
