When it comes to choosing the best pick among Gems for Libra gemstones, Prehnite is known to be a popular choice!Physical properties of Prehnite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Prehnite 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. Prehnite cleavage is nothing but the plane across which the crystal splits during cutting. Prehnite cleavage is Distinct on [001],and specific gravity of Prehnite is 2.80-2.95.
The physical properties of Prehnite, 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 Prehnite is represented by Ca2Al2Si3O12(OH).
