When it comes to choosing the best pick among Semi Precious Gemstones gemstones, Peridot is known to be a popular choice!Physical properties of Peridot include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Peridot 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. Peridot cleavage is nothing but the plane across which the crystal splits during cutting. Peridot cleavage is Poor,and specific gravity of Peridot is 1.54-1.55.
The physical properties of Peridot, 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 Peridot is represented by (Mg,Fe)2SiO4.
