Both are ⅜-inch stone — the difference is shape: #89 is angular crushed granite that locks in place, while pea stone (Riverbed ⅜") is smooth, rounded river stone that's easier on bare feet and paws. Pick by the job, not the size: crushed edges knit together under traffic, while rounded stone rolls and spreads unless something contains it.
