Okay, I am thinking of a bezel effect and can't think of what it's called. In a bezel setting, when the bezel is not really beaded, but has more of a crimped or fluted edge like a pie crust...what is that effect actually called? I feel like I've seen it on a Daniel M setting or similar.

Edited to add: And I don't mean milgrain (although that is also delicious).

hmmm, are you thinking of an "illusion" setting?

something like this:

A buttercup setting perhaps? ~Red

Can you post a link to the daniel m ring that you saw this on?

possibly fish-tail prongs?

Fluted Bezel?
