River Rock, Cobble, & Beach Pebbles

River rock and cobble come in many different colors, shapes and sizes. They do share one very important feature - they are naturally more smooth or round in texture and appearance as they have been shaped by the forces of water and friction for thousands of years.

Beach Pebbles are found in river bottoms, lakes, streams, and are often washed up on beaches around the world. In addition to their natural occurring appearance, they can be polished to create an even smoother texture for aesthetic purposes.
