Crushed Stone vs Decomposed Granite: 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.

Decomposed Granite

Decomposed granite, or DG, is granite that weathered in the ground into a mix of sand, silt, and small chips, then was dug and screened to 1/4 or 3/8 inch minus. It costs $25 to $45 per ton in 2026, weighs 1.3 to 1.5 tons per cubic yard, and compacts into a firm, natural-looking path or patio surface in gold, tan, gray, or rose. It is the standard path material in California, Arizona, Texas, and most of the drought-tolerant West.

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.

Decomposed Granite

Decomposed granite is a mix of sand-sized particles and small granite chips, usually 1/4 inch minus, sometimes 3/8 inch minus. Colors run gold, tan, buff, gray, brown, and rose depending on the quarry. Gold and tan are the standard California and Arizona look. Sold loose, or stabilized with a binder that is mixed in dry or applied as a liquid.
