When it comes to choosing the best pick among Semi Precious Gemstones gemstones, Jade is known to be a popular choice!Physical properties of Jade include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Jade 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. Jade cleavage is nothing but the plane across which the crystal splits during cutting. Jade cleavage is 1 or 2,2 prismatic.,and specific gravity of Jade is 2.90-3.38.
The physical properties of Jade, 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 Jade is represented by Nephrite: Ca2(Mg,Fe)5Si8O22(OH)2 Jadeite: NaAlSi2O6.
