When it comes to choosing the best pick among White Gemstones gemstones, Cancrinite is known to be a popular choice!Physical properties of Cancrinite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Cancrinite 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. Cancrinite cleavage is nothing but the plane across which the crystal splits during cutting. Cancrinite cleavage is Perfect on , poor on ,and specific gravity of Cancrinite is 2.42-2.52.
The physical properties of Cancrinite, 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 Cancrinite is represented by Na 2Ca 2Al 6Si 6O 24(CO 3) 2Walter Schumann , Gemstones of the world (2001) More from other references.
