Hello, I use a company in California that I think does really great
castings. They are Quackenbush Production Goldsmiths. Their number
is 530-274-2777. The owner is Paul Quackenbush. You may also speak
with Karen, who is the number 2 there. They do great work quickly. I
have them cast a lot of things for me in my production alloy, but
sometimes I just need a one off in white gold or silver and they do
that for me just as quickly.
Good luck, Dennis
