When it comes to choosing the best pick among Blue Gemstones gemstones, Cordierite Iolite is known to be a popular choice!Physical properties of Cordierite Iolite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Cordierite 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. Cordierite Iolite cleavage is nothing but the plane across which the crystal splits during cutting. and specific gravity of Cordierite Iolite is 2.56-2.66.
The physical properties of Cordierite 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 Cordierite Iolite is represented by Mg 2Al 4Si 5O 18Ulrich Henn and Claudio C..
