Luxurious, natural, and 100% original, Sliced Pebble Mosaic (TM) products feature natural Indonesian beach pebbles which are precision sliced into 1.0mm (3 / 8") sections. These sliced sections are professionally tumbled then painstakingly placed within the mosaic by our staff of artisans then bonded to a double scrim netting, creating an easy-to-install tile alternative.
