When it comes to choosing the best pick among Brown Gemstones gemstones, Jacobsite is known to be a popular choice!Physical properties of Jacobsite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Jacobsite 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. Jacobsite cleavage is nothing but the plane across which the crystal splits during cutting. Jacobsite cleavage is None,and specific gravity of Jacobsite is 4.76-5.03.
The physical properties of Jacobsite, 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 Jacobsite is represented by (Mn2+ ,Fe2+ ,Mg)(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001).
