Natural River Stone Rock

We carry a large line of unpolished natural river stones. They are available in a multitude of sizes and river stone colors. The river stone colors are gray, white, blue, green, peach or a mix of all colors together.

Natural River Stone Source

River Stones like cobbles and boulders are likely to be found in mountain valley streambeds. Cobbles are also transported by glaciers and deposited as with other grades of sediment as till. If the till is water-laid, finer particles like sand and pebbles may be entirely washed away, leaving a deposit of only boulders and cobbles.

    River pebble stones are naturally available in colors of white, beige, light gray, blue and dark gray.


cobble

A cobble (sometimes a cobblestone) is a clast of rock defined as having a particle size of 64–256 millimeters. Some cobbles have been scoured by water flow for many decades, so they are smooth and fully-rounded. Others have been scoured by water flow for less time, so they are not so smooth but only half-rounded.

Fully-rounded Cobble

  • fully-rounded cobble

    These are fully-rounded cobbles in typical colors of white, beige, gray and blue.


Half-rounded Cobble

  • half rounded cobble

    These are half-rounded cobbles in typical colors of white, beige, gray and blue.
