When it comes to choosing the best pick among Blue Gemstones gemstones, Glaucophane is known to be a popular choice!Physical properties of Glaucophane include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Glaucophane 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. Glaucophane cleavage is nothing but the plane across which the crystal splits during cutting. Glaucophane cleavage is Good on [110] and on [001],and specific gravity of Glaucophane is 3-3.15.
The physical properties of Glaucophane, 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 Glaucophane is represented by [ ]Na2(Mg3Al2)Si8O22(OH)2.
