Lodi Gem & Mineral Society
Gem and mineral society of Lodi with a junior program. Meetings on the second Monday of the month at 6 PM at 320 N. Stockton Street, Lodi. The club held a tailgate rock sale and swap for rockhounds, slabbers and cabbers at the Lodi Grape Festival Grounds on April 18, 2026, and leads trips with the other clubs of the Co-op, such as the visit to the California State Mining and Mineral Museum in Mariposa on December 12, 2026.
Around here, the land is mostly private
Within 50 miles of Lodi our maps show no open public land to prospect. That is exactly why a club matters here: clubs have the landowner permissions, the leases and the know-how.
Nearest open public land on our gem and mineral map: about 62 miles away.
