When it comes to choosing the best pick among Colorless Gems gemstones, Beryllonite is known to be a popular choice!Physical properties of Beryllonite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Beryllonite 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. Beryllonite cleavage is nothing but the plane across which the crystal splits during cutting. Beryllonite cleavage is perfect; good, interrupted; indistinct; in traces,and specific gravity of Beryllonite is 2.79-2.87.
The physical properties of Beryllonite, 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 Beryllonite is represented by NaBePO 4Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
