The goal of the San Diego Mineral and Gem Societies' Museum is to help people gain a better understanding and appreciation of minerals, gems, fossils and the lapidary arts. Our museum is located in the San Diego Mineral & Gem Society building adjacent to the Spanish Village Art Center at Balboa Park, San Diego, California. The Museum features many fine mineral, gem, lapidary and fossil specimens from around the world. The collection has been assembled over the last 75 years through purchases and donations. Admission to the Museum is free.

The San Diego Mineral & Gem Society 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. Access from Village Place. (Note: the road between Otto Center and Spanish Village is an alley, signage: "no pedestrians").
