When it comes to choosing the best pick among Colorless Gems gemstones, Oligoclase is known to be a popular choice!Physical properties of Oligoclase include its hardness, gravity, fracture, cleavage, etc. For any gemstone crystal, Oligoclase 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. Oligoclase cleavage is nothing but the plane across which the crystal splits during cutting. Oligoclase cleavage is From the Greek, oligos and kasein, little cleavage.,and specific gravity of Oligoclase is 2.62-2.67.
The physical properties of Oligoclase, 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 Oligoclase is represented by Na(90-70%)Ca(10-30%)(Al,Si)AlSi 2O 8Michael OâDonoghue , Gems, Sixth Edition (2006).
