Fog Dancer - have you seen the Lark 500 books? I think you would really enjoy the jewelry ones - there have been books dedicated to rings, wedding rings, bracelets, necklaces, etc. Very interesting pieces.
the first three rings are fantastic! as I really appreciate simple and bold designs. Love the last one for a man. The second reminds me of a prong/semi bezel hybrid, and I bet you won't catch much on those.
