Crushed Stone vs. Crushed Gravel: What’s the Difference

Crushed Gravel. The primary difference between crushed stone and gravel is that gravel is not man-made. It forms naturally from large rocks, which erode over time, creating smaller rocks. As a result, crushed gravel is typically rounder and has a smoother shape than crushed stone.
