Wow - I found so much information out there for us jewelry makers! Several places to get started -
about.com has a wonderful selection of articles for jewelry makers, as well as a jewelry makers forum.
the jewelry link exchange for getting some links added to your site, plus plenty of links to purcase your supplies and look around at what others are doing.
Then there's the International Jewelry Designers Guild, they have a group in yahoo, and loads of information and links.
I've also created my own group in Google called Jewelry Artists Designers Here's the link:

Take a good look, if you're looking for information. It's certainly out there!
