A high gloss polish is achieved by grinding the surface of the stone with a series of increasingly fine diamond grit pads or compounds. A final process using Oxalic acid or a crystallizing compound is sometimes used to increase the mirror-like effect.
Marbles, granites and some of the harder, fine-grained limestones can be polished. This gives a smooth and reflective finish and brings out all the subtleties and beauty of the stone.
