When it comes to choosing the best pick among Violet Gemstones gemstones, Foitite is known to be a popular choice!Physical properties of Foitite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Foitite 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. Foitite cleavage is nothing but the plane across which the crystal splits during cutting. Foitite cleavage is None,and specific gravity of Foitite is 3.17.
The physical properties of Foitite, 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 Foitite is represented by Na x[Fe2+2(Al,Fe3+ )]Al 6(BO 3) 3Si 6O 18(OH) 4Anthony et al , Handbook of mineralogy (2001).
