Hinged Nose ring

Hello All, I have a custom order for a channel set diamond nose ring
in 14kt gold and I have attempted a couple of different hinges but
have not be able to quite get it. I want the hinge to not open all
the way,just enough to fit over the nose then connect to the wire
kind of like the hug earrings. If anyone knows of a good book about
this type of hinge or is able to explain it via email I would
greatly appreciate it. Thanks All! Ann in PDX, OR
