Wearing a ring of stealth gives you extrinsic Stealth. If polymorphed in to a creature that is capable of eating jewelry and the ring is of suitable material, you may eat this ring and may gain Stealth as an intrinsic.
Note that unlike elven boots, a ring of stealth does not give any special message to indicate that you are stealthy, making it more difficult to identify. To test if a given ring is stealth, you can check if putting on elven boots gives a message or if monsters in a zoo/graveyard/throne room wake you when you enter.
