When it comes to choosing the best pick among Colorless Gems gemstones, Bertrandite is known to be a popular choice!Physical properties of Bertrandite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Bertrandite 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. Bertrandite cleavage is nothing but the plane across which the crystal splits during cutting. Bertrandite cleavage is Perfect, Distinct, Distinct,and specific gravity of Bertrandite is 2.59-2.60.
The physical properties of Bertrandite, 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 Bertrandite is represented by Be 4Si 2O 7(OH) 2Anthony et al , Handbook of mineralogy (2001).
