S F Gem & Mineral Society

I’ve been a member for a while, and the SF Gem and Mineral Society is an amazing organization. In addition to scheduling digs to get materials, they have all the equipment you need for any type of lapidary project. Basically, it’s an artisan co-​op, and membership rates are really cheap– about $ 25 year. Visit
for more information.

I moved away from San Francisco and the Outer Sunset before I could join :(If you do you can take jewelry and lapidary (stone and gemstone finishing) classes as well as use their tools for your projects.
They seem to have a very active, as well as informative, website where they update regularly on lectures and meetings. If you want to learn more about rocks and minerals this is the place to be.
The only time I stepped into their space down at the end of Judah was when they had an open house type of thing where many of the members were selling their amazing jewelry and stone work.
I had never noticed the place before, and they’re not exactly open to the public, so check the website (I just added it to Unilocal — so it should show up on their info soon) and go to one of their scheduled meetings or lectures to learn more about what they do and how you can join up.
