Herderite Cleavage
When it comes to choosing the best pick among Colorless Gems gemstones, Herderite is known to be a popular choice!Physical properties of Herderite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Herderite 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. Herderite cleavage is nothing but the plane across which the crystal splits during cutting. Herderite cleavage is Indistinct on ,and specific gravity of Herderite is 2.90-3.02.
The physical properties of Herderite, 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 Herderite is represented by CaBePO 4(F,OH)Ulrich Henn and Claudio C..
