I do not know whether the Ring of Barahir had any power. It belonged to Finrod. He gave the ring to Barahir as a pledge of aid to his house. And when Beren came to Nargothrond for that aid, Finrod gallantly went forth to his doom in the Quest of the Silmaril.
The ring was an elven-ring, made by the Noldor in Valinor.
The ring was in the fashion of two serpents with emerald eyes, one devouring and the other, supporting a crown of gloden flowers.
