Decomposed Granite vs Stone Dust: Size, Cost, and Which to Use
Decomposed Granite runs about $25 per ton and Stone Dust about $15 per ton. Compare size, drainage, compaction, and which one to use.
Overview
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.
Stone dust is a finely crushed aggregate made up of stone particles smaller than 1/4 inch. It compacts tightly when installed and lightly moistened, creating a firm, smooth surface ideal for leveling and base preparation.
