When it comes to choosing the best pick among Blue Gemstones gemstones, Nosean is known to be a popular choice!Physical properties of Nosean include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Nosean 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. Nosean cleavage is nothing but the plane across which the crystal splits during cutting. Nosean cleavage is Perfect,and specific gravity of Nosean is 2.30-2.40.
The physical properties of Nosean, 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 Nosean is represented by Na 8Al 6Si 6O 24(SO 4) · H 2OAnthony et al , Handbook of Mineralogy (2001).
