Crushed Stone vs River Rock: Size, Cost, and Which to Use

Crushed Stone

Crushed stone is rock that a quarry blasted, crushed, and screened into a set size range. It costs $20 to $40 per ton in 2026, weighs 1.35 to 1.55 tons per cubic yard, and is the base under nearly every road, driveway, slab, and patio in the country. The important difference from "gravel" in the natural sense is shape: crushed stone is angular, so the pieces lock together, while natural river gravel is rounded and rolls. Almost everything sold as gravel at a quarry is crushed stone.

River Rock

River rock is naturally rounded stone from river beds and glacial gravel deposits, washed and screened into size bands from 3/4 inch to 8 inches. It costs $40 to $100 per ton in 2026, weighs 1.35 to 1.6 tons per cubic yard, and is the go-to decorative stone for dry creek beds, garden beds, borders, and drainage swales where the rock needs to look good and stay put. It costs two to three times what crushed stone costs because it is sorted and washed, and because the supply is limited to places with river gravel.

Crushed Stone

Crushed stone is sold by sieve size, from stone dust and #10 screenings (under 1/4 inch) through #8 (3/8 to 1/2 inch), #57 (3/4 to 1 inch), #4 (1 to 1.5 inches), #3 (1.5 to 2.5 inches), and #1 or #2 (2.5 to 4 inches). Every size is angular with fractured faces. Color follows the quarry: gray or blue-gray limestone, gray to pink granite, dark basalt, or tan sandstone and limestone in the South.

River Rock

River rock is sold by size band: 3/4 to 1 inch (sometimes called large pea gravel), 1 to 2 inch (egg rock), 2 to 3 inch, 3 to 5 inch, and 5 to 8 inch cobbles. Every piece is smooth and rounded. Colors are a natural mix of tan, brown, gray, cream, rust, and black, with regional loads that run mostly one shade. Single-color sorted rock costs more.
