Legally engagement rings are supposed to go back to you. If it was enough money you could sue her for it if you felt like being a real thingyhead.
really depends on how much of a pregnant dog she was in breaking off the engagment. but lets not throw this off into that direction, we'll scare DSR off.
DSR, if there is something she really likes, something she collects, tie the ring in with that somehow. Even a small stuff animal with the ring around it's neck would be memorable.
