Re: Help: Simple, clean, setting like Tiffany's Asscher sett
It's a pretty standard cathedral basket setting. It won't allow for a flush fit (or even a close fit) wedding band, so you need to be aware of that. Otherwise, just about any vendor can get a custom piece exactly like it. I don't think that design would be copyright protected as it is very generic (not in any bad sense of the word, just in the legal sense). I would just call around to whichever of the PS CAD and CAST vendors you like and see what they quote you.
