When it comes to choosing the best pick among Grey Gemstones gemstones, Nifontovite is known to be a popular choice!Physical properties of Nifontovite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Nifontovite 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. Nifontovite cleavage is nothing but the plane across which the crystal splits during cutting. Nifontovite cleavage is Indistinct,and specific gravity of Nifontovite is 2.35-2.36.
The physical properties of Nifontovite, 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 Nifontovite is represented by Ca 3B 6O 6(OH) 12 · 2H 2OAnthony et al , Handbook of Mineralogy (2001).
