When it comes to choosing the best pick among Green Gemstones gemstones, Strontianite is known to be a popular choice!Physical properties of Strontianite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Strontianite 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. Strontianite cleavage is nothing but the plane across which the crystal splits during cutting. Strontianite cleavage is Good,and specific gravity of Strontianite is 3.63-3.79.
The physical properties of Strontianite, 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 Strontianite is represented by SrCO 3Walter Schumann , Gemstones of the world (2001) More from other references.
