The Ring of Barahir:

Given to Barahir by the Elven lord Finrod as a gift of thanks for saving his life, the ring became a sign of eternal friendship between their houses. Passed to Beren and eventually Elendil, the ring was seen as an heirloom of the Dunedain and was worn by the Kings of Arnor until the death of Arvedui. It was ransomed by the Dunedain of the North from the Lossoth and kept safe at Rivendell, given to Aragorn by Elrond upon the revelation of his true heritage.
