Iolite Cleavage
When it comes to choosing the best pick among Gems for Taurus gemstones, Iolite is known to be a popular choice!Physical properties of Iolite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Iolite 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. Iolite cleavage is nothing but the plane across which the crystal splits during cutting. Iolite cleavage is 3,1,and specific gravity of Iolite is 2.6-2.7.
The physical properties of Iolite, 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 Iolite is represented by Mg2Al4Si5O18.
