Looking for a used setting

[daintyG]

I am looking for something to set my 5.3 mm round diamond in. I would be happy with a pave or solitaire style ring. What's most important to me is that it doesn't cost much. A simple setting is fine, especially because my diamond is really pretty on its own! I am thinking I should look for used settings to keep cost down. I also contacted DanielM two days ago to ask about a silver setting, but I have not heard back so far. I got my stone at GOG and could always get their least expensive solitaire, but I am wanting to explore my options.

If you know of anything I could consider, please pass it along. Thanks in advance!
