Narragansett: Beryl & Quartz Rockhounding in South County, Rhode Island
Updated July 2026
The pegmatite outcrops along the Bonnet Shores coast in Narragansett carry beryl and quartz in coarse granitic pods, a rare chance to see gem-family minerals in place on a public Rhode Island shore. Pale blue-green aquamarine beryl has been reported from the pegmatites of the state's western granites, and the wave-cut ledges here expose that rock directly. Both the ledges and the pebble beach below reward careful searching. Reported finds include beryl, quartz. Below: coordinates, access notes, nearby spots, and trip-planning links.

Land & collecting status
Generally open to casual rockhounding
Most public-tagged spots sit on BLM, U.S. Forest Service, or other federal land where reasonable hand collecting of common rocks and minerals is allowed. Confirm posted rules and active mining claims before you dig.
Public-land rules vary by agency, season, and field office. The RockHoundR app pulls live BLM, USFS, NPS, and tribal overlays so you can see exactly which agency manages the ground at this spot.
Sources & verification
Spot details combine the public RockHoundR location dataset, normalized mineral labels, agency land-status checks in the app, and community submissions. Coordinates are approximate until verified in the field.
