Sierra Cobble Stone 2" - 4"
These Southern California river pebbles and cobbles are know for cool blue, soft grey and tan colors. This rock improves with age as the small amounts of river sand residue washes out of the stone.
These stones have a wide variety of uses, including creek beds, rock veneers on houses, rock pillars, fireplaces, fences, planters, fountains and retaining walls. This stone is silver and gray in color with brown and rust tones. These beautiful river rock pair nicely with our granite boulders or many of our natural stones in creek beds.

Tons vs. Yards and Square Feet.
In most cases we charge by the ton and we have the receipts from the scale house at the quarry to show upon request. Materials sold by the yard tend to have very in-accurate amounts in the trucks. Amounts depend the size of the loader bucket, how well the material was scooped up and who was supervising the loading of the truck. Scale House totals don't lie, so why take a chance on losing money and time with how many square feet, scoops, skips and or dumps were made in loading the truck?
