Polishing is defined as placing a high reflective finish on the surface of the stone. Polishing is usually accomplished with super fine abrasive

powders but, can also be achieved with super-fine diamond abrasive discs


The deep shine we see on polished stone is achieved by rubbing the stone with a series of abrasive materials. The process is very similar to

sanding a piece of wood. The stone is rubbed with a coarse abrasive grit, followed by finer and finer grits until the stone becomes smooth.


The scratches left behind from one grit are removed by the next, creating finer and finer scratches. The process continues until the scratches are microscopic. The shine on the stone is achieved by abrading the surface to the point at which it becomes extremely smooth and starts to developsome reflectivity. The shine on the stone is thus a product of optics.
