When it comes to choosing the best pick among Gems Found In Africa gemstones, Sogdianite is known to be a popular choice!Physical properties of Sogdianite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Sogdianite 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. Sogdianite cleavage is nothing but the plane across which the crystal splits during cutting. Sogdianite cleavage is Perfect,and specific gravity of Sogdianite is 2.77-2.90.
The physical properties of Sogdianite, 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 Sogdianite is represented by (K,Na) 2(Li,Fe) 3(Zr,Ti,Fe)Si 12O 30Ulrich Henn and Claudio C..
