When it comes to choosing the best pick among Black Gemstones gemstones, Pyrargyrite is known to be a popular choice!Physical properties of Pyrargyrite include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Pyrargyrite 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. Pyrargyrite cleavage is nothing but the plane across which the crystal splits during cutting. Pyrargyrite cleavage is Distinct on , imperfect on ,and specific gravity of Pyrargyrite is 5.85.
The physical properties of Pyrargyrite, 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 Pyrargyrite is represented by Ag 3SbS 3Michael OâDonoghue , Gems, Sixth Edition (2006) More from other references.
