My wife has a "stunt ring" that she wears instead of her wedding ring in Negril. No point bringing the expensive original ring that we would be upset over if lost.

Me, I wear my wedding band, because it is only titanium and not worth much. However, when I snorkel my finger shrinks 2 sizes and the ring slides right off. When i'm in the water I usually put it in a back pack and keep it somewhere where it is being watched
