Stone Forest president Michael Zimber can often be found collecting pebbles at the beach or along a river. His lifelong hobby has manifested in the form of a vessel sink collection that is designed to look like enlarged, smooth pebbles. The sinks measure 4-½” by 24” by 13 ¾” and are available in three materials: Nero Marquina marble, sandstone, and a stone conglomerate called Jurassic. stoneforest.com
