When it comes to choosing the best pick among Green Gemstones gemstones, Pargasite is known to be a popular choice!Physical properties of Pargasite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Pargasite 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. Pargasite cleavage is nothing but the plane across which the crystal splits during cutting. Pargasite cleavage is perfect,and specific gravity of Pargasite is 3.04-3.26.
The physical properties of Pargasite, 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 Pargasite is represented by NaCa 2(Mg 4Al)Si 6Al 2O 22(OH) 2Michael OâDonoghue , Gems, Sixth Edition (2006).
