Fëanor creates three Silmarils in J.R.R. Tolkien’s legendarium.
The Silmarils are jewel-like objects made by the Elven craftsman Fëanor during the First Age. They contain the light of the Two Trees of Valinor, Telperion and Laurelin, before those trees are destroyed. Their beauty and sacred light make them the most treasured works of Fëanor’s craft.
Morgoth steals the three jewels and sets them in his iron crown. Fëanor’s oath to recover them drives the rebellion of the Noldor and much of the conflict recorded in The Silmarillion. The jewels remain central to the long wars of Beleriand.
The Silmarils are not simply valuable gems. They cannot be destroyed by ordinary means, and their light is associated with the lost Two Trees. Their story also differs from that of the One Ring: the Silmarils are three ancient jewels, while the Ring is a later instrument made by Sauron.
