When it comes to choosing the best pick among Semi Precious Gemstones gemstones, Tanzanite is known to be a popular choice!Physical properties of Tanzanite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Tanzanite 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. Tanzanite cleavage is nothing but the plane across which the crystal splits during cutting. Tanzanite cleavage is Perfect , imperfect ,and specific gravity of Tanzanite is 3.35.
The physical properties of Tanzanite, 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 Tanzanite is represented by Ca2Al3(SiO4)3(OH).
