Orange Belt Mineralogical Society (OBMS)

Established in 1933.  A non-profit club of rock enthusiasts who hunt for rocks, develop their lapidary skills, and fabricate jewelry and rock artifacts in a workshop in San Bernardino, California.

We organize hunts for rocks, teach lapidary, wire wrapping, silversmithing, and lost wax casting skills.

We invite you to join us
at the workshop for our MONTHLY

    OBMS members have a BBQ on the 2nd Saturday of every month. This is a good time to come on down and tour the workshop.  You can start working with stone, on a nice piece of jewelry or that rock you've been meaning to cut while enjoying some good food with good people. 

    Bring a favorite dish that you know everyone will like.  Bring a friend.  Enjoy the warm and friendly atmosphere of fellow rock hounds. Like always, donations are welcome.
