North Providence: Bowenite & Quartz Rockhounding in Providence County, Rhode Island
Updated July 2026
The serpentine belt running through northern Rhode Island is the home of bowenite, the state mineral, a hard translucent green serpentine close enough to jade to be cut as a gemstone. It was first described here in the early 1800s by George Bowen, and the North Providence and Lincoln limestone country remains the classic ground for it. No other state claims bowenite, which makes this belt the defining mineral destination in Rhode Island. Reported finds include bowenite, quartz, serpentine.

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.
