The San Luis Obispo Gem and Mineral Club is a nonprofit organization that promotes mineralogy, earth sciences and allied subjects such as the lapidary arts. Membership is open to all who share those goals.

Some of the areas that are explored by the club include:

  • Earth sciences (geology)
  • Rocks, minerals, gems, fossils (identifying, collecting, displaying, field trips)
  • Lapidary crafts (cabbing, tumbling, faceting, carving)
  • Related crafts (beading, wire wrapping, metal smithing, jewelry making)

Members in good standing get email notifications of upcoming club field trips. These trips involve finding local gems and minerals with knowledgeable guides who can identify the discoveries and share insider tips.

Monthly meetings include presentations from local experts, show and tell, and rock and mineral identification.

Everyone is welcome to join the club. A portion of the yearly dues go to CFMS – the California Federation of Mineralogical Societies and the rest covers insurance for the club’s annual Gems by the Sea rock and gem show in September.
