Vilya, Ring of the Elves

Along with Nenya and Narya, Vilya was often referred to as one of the Three Rings of the Elves, the mightiest of the Three. Celebrimbor, lord of Eregion forged all three independent of Annatar, a guise of the Dark Lord Sauron. As a result of this, none of the Three were stained by his evil. However, like all the Rings of the Elves, Vilya was still under Sauron's influence when he wielded The One Ring, which held dominion over all the others.  Like the other Rings of Power, Vilya was jewelled: it contained a great blue stone set in a gold band, which contributed to its titles of the Ring of Sapphire and the Blue Ring. A lesser-used title of Vilya was the Ring of Air, signifying its pre-eminence even over the other Rings of the Elves; it was generally considered that Vilya was the mightiest of these three bands.  Wikki
