When it comes to choosing the best pick among Blue Gemstones gemstones, Cordierite is known to be a popular choice!Physical properties of Cordierite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Cordierite 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 cleavage is nothing but the plane across which the crystal splits during cutting. Cordierite cleavage is Fair on , poor on and ,and specific gravity of Cordierite is 2.57-2.66.
The physical properties of Cordierite, 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 is represented by Mg2Al4Si5O18.
