Welcome to Our Club

Welcome to the Contra Costa Mineral & Gem Society. We have been serving the Contra Costa mineral and gem and lapidary community for over 50 years. We meet monthly in Concord at the Centre Concord, 5298 Clayton Blvd.

 

We have monthly lapidary classes and informative field trips for rockhounds and geologist alike. And the monthly programs are superb.

 

Come join us for an evening with great people and outstanding programs the second Monday of each month (third in June) at 7:30 pm.

 

President, CCM&GS
