[Source] [SF] Casting and stone setting

Hi - I am currently in NYC and have access to the diamond district
whereI can send small jobs to a local casting company & stone
setter. I’m considering a move to the SF Bay Area and would like to
find a caster & stone setter that I can use there. I’m not sure if
SF or even Oakland has a similardistrict where I can find similar

Any recommendations are greatly appreciated.
