When it comes to choosing the best pick among Red Gemstones gemstones, Franklinite is known to be a popular choice!Physical properties of Franklinite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Franklinite 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. Franklinite cleavage is nothing but the plane across which the crystal splits during cutting. Franklinite cleavage is None,and specific gravity of Franklinite is 5.05-5.22.
The physical properties of Franklinite, 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 Franklinite is represented by (Zn,Mn2+ ,Fe2+ )(Fe3+ ,Mn3+ ) 2O 4Anthony et al , Handbook of mineralogy (2001).
