When it comes to choosing the best pick among Green Gemstones gemstones, Andradite is known to be a popular choice!Physical properties of Andradite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Andradite 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. Andradite cleavage is nothing but the plane across which the crystal splits during cutting. Andradite cleavage is none,and specific gravity of Andradite is 3.70-4.10.
The physical properties of Andradite, 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 Andradite is represented by Ca 3Fe 2(SiO 4) 3Arthur Thomas , Gemstones (2009).
