I think I have found my diamond (yay!) and now I just need the setting. I am looking for a vintage style cathedral (engagement ring only) setting that has scroll (swirly) style engraving and milligrain edges. No additional stones, just a solitaire with the engraving.I tried to find a local hand engraver since I found a setting that I liked (see link) that is plain, but there are none local. I will be checking local antique shops as well but thought I''d see if anyone here had any info about where to find something like this. Any help appreciated! Thanks a bunch!
