When it comes to choosing the best pick among Blue Gemstones gemstones, Riebeckite is known to be a popular choice!Physical properties of Riebeckite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Riebeckite 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. Riebeckite cleavage is nothing but the plane across which the crystal splits during cutting.
