Pawtuxet: Agate & Carnelian Rockhounding in Providence County, Rhode Island

Updated July 2026

The Narragansett Bay beach gravels at Pawtuxet Village turn up agate, carnelian, amethyst, and jasper pebbles, the same chalcedony suite that washes out of the region's volcanic and glacial deposits. Pawtuxet Park and the public shore at Pawtuxet Cove give walk-in access to a productive cobble beach inside the metro area. It is one of the most convenient bay shorelines in the state for surface pebble hunting. Reported finds include agate, carnelian, amethyst, jasper.
