Blue Ring

Vilya, one of the Three Rings of the Elves, and said to be the mightiest of those three Elven-rings. In form it was a golden ring set with a blue sapphire, hence the name Blue Ring, but it had other names besides: the Ring of Air and, naturally, the Ring of Sapphire. Its maker Celebrimbor sent it originally to King Gil-galad in Lindon, but Gil-galad passed it on to Elrond to aid the founding of Rivendell. At the end of the Third Age, Elrond had borne the Blue Ring for nearly five thousand years.
