A gift is completed if there is donative intent and delivery. She wanted you to have it, and gave it to you, so I think this is a completed gift. Furthermore, if you were to give it back, you would have to have work done to your wedding ring. If you sister is very wealth, and very litigious, I'm sure she could find somebody to try a lawsuit for the return of the ring. And it would be a very interesting lawsuit.
