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.

Access note: Public rocky shoreline. Rhode Island shoreline access rights allow passage and collecting of loose material along the beach and wet rock zone; the law does not extend onto private lawns, sea walls, or the tops of rocky cliffs. Take loose float and pebbles, do not hammer the ledges within any conservation or association property.

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.
