Narsil:

The sword of Elendil, it was forged by Telchar in Beleriand during the First Age of the Sun. The Narsil was broken at Elendil's death upon the slopes of Orodruin. Isildur used the hilt-shard to cut the One Ring off of Sauron's hand.

The shards were ofttimes carried by the Heir of Isildur. The shards of the Narsil were reforged in the year 3018 for Aragorn who then called the sword Andúril.

Nenya:

One of the three Elven-Rings made by Celebrimbor, Nenya was the Ring of Water, the Ring of Adamant, the Ring of Mithril. The keeper of Nenya was Galadriel. As one of the Keepers of the Three, she took Nenya into the West in the year 3021 of the Third Age of the Sun. Only the Three were made without the influence of Sauron.

Narya:

One of the three Elven-Rings made by Celebrimbor, Narya was the Red Ring, the Ring of Fire. The first keeper of this ring was Círdan, but he gave it to Gandalf. As one of the Keepers of the Three, Gandalf took Narya into the West in the year 3021 of the Third Age of the Sun. Only the Three were made without the influence of Sauron.
