Hello Guy, Welcome. For my gold/silver materials and refining I use
David H Fell and Co. They are a family based business, and I’ve had a
very good experience working with them since the 70’s. Good folks and
I’m sure you’ve heard that the jewelry mart in downtown LA is where
most of the wholesalers are located? (Beth, are you reading this? I
know you know this warren of businesses)
I like Herco, based in SF for chain and gold coils. Good catalogue,
excellent service, via ups or fedex.
For findings, I go between Stullers and Rio. Between them I can find
most things, a range of qualities and karats.
I don’t know anything about setters, casting and use mostly recycled
Kind regards, Marianne
