River Rock vs Stone Dust
Side-by-side comparison of River Rock and Stone Dust to help you choose the right gravel for your project.
Overview
Naturally rounded stones smoothed by water erosion. Available in sizes from 1 to 5+ inches. River rock adds a polished, natural look to any landscape and is prized for its smooth texture and visual appeal.
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.
