Santa Rosa Mineral And Gem Society, INC
Northern California's Rockhound Hangout

The Santa Rosa Mineral and Gem Society is a non-profit organization, located in Sonoma County, CA. and formed for the purpose of increasing the knowledge and understanding of science as it pertains to the study of minerals, gems, and fossils. We study geology, mineralogy, archeology, paleontology, and all the lapidary arts. We encourage the interest of our Junior Members, and reach out to the community throughout the year to share our interest and knowledge.

To further answer the call of the community we have expanded our website to provide more resources, and to attract people of all ages to the study of "rocks".
