When it comes to choosing the best pick among Green Gemstones gemstones, Antigorite is known to be a popular choice!Physical properties of Antigorite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Antigorite 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. Antigorite cleavage is nothing but the plane across which the crystal splits during cutting. Antigorite cleavage is Good,and specific gravity of Antigorite is 2.58-2.80.
The physical properties of Antigorite, 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 Antigorite is represented by (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001).
