My grandmother never, ever, took off her wedding band. It was worn almost away when she died. The first thing my mother did when she got married was take off her wedding ring so should wouldn't get that superstitious about it. She wears it most of the time but doesn't feel so attached to it that she can't take it off.

I've got a silver ring I wear on my right hand (high school graduation present) that I feel weird without just because I'm used to the feel of it on my hand, but I don't "need" it psychologically.
