There was a huge thread in the past...I don't recall the name exactly, but everyone posted their urls for ring settings there..all types. You may want to search the archives for it. It was something like 'Compilation of Ring Settings' and it was huge.
Thank you Mara and Hest! A few of the sites you mentioned were new to me, and Google was slightly better than Yahoo....more in presentation than content. The "Compilation" thread is huge, but not specifically about antique style settings.
If anyone out there has more links to add they would be sooooooo appreciated! Then this will become the thread everyone refers back to for antique settings!
