You can buy polished and cut stones from dealers online. I have a friend who has one she recommends; I'll have to dig it out. Beyond that though you can get settings lots of places. It is of course easier to get Sterling silver or other non-precious settings.
I did some silverworking when I was overseas, but have not done it for a long while - and have never done it locally. I mostly used the common tools at my old instructor's shop and don't think I brought back any of the tools I owned with me during the move home (shoot!)....but, I can talk with you about techniques if you want, and show you some finished pieces for ideas. (rings, earrings, pins, and some very limited wax method work).
What did you have in mind?
Basic tool list might include
keyhole wood wedge with table clamp (I don't know the technical terms in English for some of this stuff, so bear with me)
goop (?) used for polishing (it's gray and is about as thick as Crisco)
gas table
flux and silver bits
long pinchers
long clamps that are closed by default
large asbestos shingle or equivalent
several grades of flat and rounded files
hammer(s), some round, varied sizes
saw(s) - really small ones
obviously - eye protection
If you decide to make a ring, you'll need a metal ring sizer
raw materials - silver 926, if I'm remembering correctly
Big time equipment includes a polisher on a base, and a few other things, but we could probably figure something out.
I will keep an eye out for lessons or an open-to-the-public silverworking shop in town. In the meantime, if you decide what you want to make, the design could be based on the tools available....
What do you think?
Sounds interesting.
