Question about a type of ring?

[user_08012015]

There is this ring that I've been looking for, but I can't find the name of it. I have a picture below. Not that specific ring but just the type. I love the look of them. Can anyone help me out

Those are channel set style rings

The top is a channel set, the bottom is pave set stones in a channel style ring.
