When it comes to choosing the best pick among White Gemstones gemstones, Montebrasite is known to be a popular choice!Physical properties of Montebrasite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Montebrasite 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. Montebrasite cleavage is nothing but the plane across which the crystal splits during cutting. Montebrasite cleavage is Perfect, Good, Distinct,and specific gravity of Montebrasite is 2.98-3.10.
The physical properties of Montebrasite, 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 Montebrasite is represented by LiAl(PO 4)(OH,F)Walter Schumann , Gemstones of the world (2001) More from other references.
