Official page of the San Diego Mineral & Gem Society (SMDG). The collection has been assembled over the last 75 years through purchases and donations.

Founded in 1934, SDMG's mission is to disseminate knowledge of mineralogy and earth sciences; to encourage the study of these subjects; to conduct classes in mineralogy and lapidary arts; to conduct field trips for the collection and study of specimens; to encourage interest in mineralogy and lapidary arts among young people; and to procure and maintain a collection related to the earth sciences and lapidary arts.. SDMG hosts Workshops led by our member volunteers who share their expertise through hands-on learning in Lapidary, Metals Fabrication and Gem faceting. Our current workshop schedule is posted online at:https://sdmg.org/class-schedule/class-schedule.pdf

Our museum is located in the SDMG building and features many fine mineral, gem, lapidary and fossil specimens from around the world. Admission to the Museum is free. The SDMG building is located at the northwest corner of Spanish Village in Balboa Park, between the San Diego Zoo to the north and the Natural History Museum to the south.
