Buyer's guide
How much do landscape boulders cost?
Straight answer: most landscape boulders in the U.S. run $100–$600 per ton at the yard, with specialty stone and freight pushing installed cost meaningfully higher. Prices swing on rock type, size class, sourcing region, and how far the truck has to drive.
Price ranges by stone type
Common colors (grey, pink, salt-and-pepper) sit on the low end; rare blues, blacks, and highly patterned pieces run higher.
The workhorse of retaining walls and edging. Weathered, moss-covered pieces command a premium over freshly quarried stone.
Denser, more colorful, and harder to quarry — so per-ton prices trend above granite and limestone almost everywhere.
Ranges reflect typical wholesale-to-retail yard pricing in North America; specialty feature boulders (5+ tons, unusual color, showpiece shape) can exceed these bands.
What drives the final number
- Size class
One-man (100–200 lb), two-man (200–700 lb), and machine-set boulders (700 lb – 5+ tons) are priced by ton, but the bigger the piece, the more expensive the equipment needed to move it.
- Freight
A flatbed load usually caps around 22–24 tons. Expect $4–$8 per loaded mile for dedicated hauls; 150+ mile deliveries can double the per-ton delivered cost of the cheapest stone.
- Sourcing region
Buying stone quarried near your project is almost always cheaper than importing a similar look from across the country — even for identical rock types.
Transparent pricing through auction
Local yards mark up boulders 2–3× over the quarry price and rarely publish freight separately. Premier Stone Auctions lists per-ton or per-piece prices from suppliers nationwide, with location shown up front so you can price freight before you bid.
