Join Us in discovering & enjoying the hidden treasures around us!

The CIGMC is a not-for-profit club that is open to all.

It was formed in1952 to foster interest and appreciation of the geological sciences, lapidary skills and jewelry arts through the presentation of educational programs and activities.

Our passion is rocks, minerals, gemstones & fossils–and it shows!

Join Us!

The Club participates in many activities, including monthly meetings and programs, fieldtrips and sponsorsip of the Annual Show.

2014 will be our 62nd Anniversary show.


We meet once a month for a business meeting, program and Show & Tell, and usually have a Kid's corner with special activities during the meetings. Guests are always welcome!

Fieldtrips are organized during the spring, summer and fall.

Our Annual Show includes 6-7 mineral/fossil dealers, 8-10 demonstrators, special displays and member exhibits, door prizes, kids area, fossil dig, and silent auctions throughout the show.

The Club has a monthly newsletter - Centrill Gems- that is mailed or emailed to members.
