Decorative Stone Rock
We deliver every gradeCobbles
Cobbles are large rounded rocks, roughly 2.5 to 10 inches across. The pieces are smooth and water-worn, shaped over time by rivers or glaciers. They're way bigger than the pea gravel or river rock you might picture. Some are a two-handed lift.
"Cobble" is a size class, not a rock type. Geologists set the range at 64 to 256 millimeters, which works out to about 2.5 to 10 inches. Any hard stone in that range counts, whether it's granite, basalt, or quartzite. Local river cobbles run cheaper than polished imports, so ask your driver what's stocked in your yard.

What people use it for
How to choose within cobbles
Read at the right distance
Pick the size that reads from where you'll see it. Fist-sized boulders in a small bed look like debris; pea-sized stone across a big front yard looks like dust.
Color that stays put
Natural stone holds its color for years. Dyed or coated pieces fade to grey after a season or two of sun.
Rounded vs. angular
Rounded stone rolls under a shoe, so it belongs inside a border. Angular stone stays put on a slope but reads harder underfoot.
