In August I joined the SDLS located near old town San Diego. It is a full workshop with classes on Cabochon cutting, Silversmith, faceting, and Steampunk creations. Here is there website link and Facebook page;
You will meat lots of nice people that have all times of good info to share about Lapidary and jewelry work. I have been working in the shop 1-2 times per week while I am here in San Diego. Please contact them or stop in during a posted time slot to see the place and join as a member.
