San Luis Obispo Gem & Mineral Club

San Luis Obispo Gem & Mineral Club We meet the second Wednesday of each month.
1445 Santa Rosa Street.
7-9 PM ABOUT OUR CLUB and HOW TO JOIN

Yes, we love rocks! We love rockhounding!

We enjoy learning about gems and minerals! The SLO Gem & Mineral Club holds monthly meetings on the second Wednesday of the month. Of course, during COVID, we held Zoom meetings. We hope we don’t have to resort to that again. Our benefits include monthly field trips, annual gem show, monthly newsletter, social events, and interesting speakers at our club meetings where we learn about lapidary arts

, rock identification, rockhounding sites, jewelry making, geology, and all things regarding Earth sciences. The San Luis Obispo Gem and Mineral Club is the oldest gem and mineral club in San Luis Obispo County, established in 1947, incorporated in 1953. We are a non-profit, nonpolitical, non-sectarian, charity-rooted educational society. Our main purpose is to share our knowledge and appreciation of Earth Sciences. We foster community, with an understanding, awareness, and love for our planet. Our members enjoy public exhibitions, lectures, video programs, demonstrations, field trips, and research. We learn rockhounding methods for collecting, identifying, and classifying rocks, minerals, fossils, as well as how to polish, mount, and display our rock specimens. Our group is keen to gain knowledge about the geology of the Central Coast. We are members of AFMS - American Federation of Mineralogical Society and CFMS - California Federation of Mineralogical Societies. We happily encourage and promote an interest in Earth and geological sciences, minerals, and the lapidary arts. Our members include gem and mineral collectors, hobbyists, gem cutters (faceting) jewelry makers, Rockhounds, and nature enthusiasts. If you are interested in rocks, gems, and minerals, you are welcome to join us!
