ZTAngel,
When I was looking for engagement/wedding band sets, I went to one of those huge engagement ring stores (Robbins Brothers... I don't know if they are only on the West Coast). I know they have a huge website that had thousands of rings to look at. I found the style for my husbands' ring on there, and he is extremely picky! However, we didn't buy them there, but had our rings custom made by my cousin, who is a jewelry broker. (I have an eternity band and his is based on an ancient beveled edged design).
Check it out, it will at least give you some ideas or pictures to take to another jewelry store....sorry if it you have already seen it!

Good Luck! I know how stressful all the wedding planning can be!
