When it comes to choosing the best pick among Gems Found In Africa gemstones, Poldervaartite is known to be a popular choice!Physical properties of Poldervaartite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Poldervaartite 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. Poldervaartite cleavage is nothing but the plane across which the crystal splits during cutting. Poldervaartite cleavage is None,and specific gravity of Poldervaartite is 2.91.
The physical properties of Poldervaartite, 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 Poldervaartite is represented by (Ca,Mn2+ ) 2(SiO 3OH)(OH)Anthony et al , Handbook of Mineralogy (2001).
