Ring of Barahir was given to Barahir by the Elven Lord Finrod Felagund, in reward for saving his life in Dagor Bragollach. It was a sign of eternal friendship between Finrod and the House of Barahir and it became an heirloom of his kin.
The ring was described as the likeness of two serpents intertwined with eyes made of green jewels. This was the symbol of the House of Finarfin. The serpents met beneath a crown of golden flowers that one upheld and one devoured. The jewels at least were crafted in Valinor and sometimes seemed to burn with green fire.
The ring is kept in Annúminás as a betrothal token of the Kingdom of Arthedain. Thus, their bearers claim to be heirs of Finarfin, and the kings of Arthedain can trace their descent from Lúthien, Fingolfin, Beor, Haleth and Hador.
