Hmmm. "The Rings of Power and the Third Age" says, "As soon as Sauron set the One Ring upon his finger they were aware of him.... Then in anger and fear they took off their rings" (emphasis mine), which implies that the rings were worn by more than one person. Or perhaps Celebrimbor had a bit of dissociative identity disorder, :^P

Go figure...the sources contradict each other! :^D
