The powerful artifacts forged by Fëanor in J.R.R. Tolkien’s mythology are the Silmarils. Fëanor created three jewels that captured the light of the Two Trees of Valinor.
The Silmarils became the central objects of the conflicts described in The Silmarillion. After Morgoth stole them, Fëanor and his sons swore an oath to recover them, an act that brought tragedy and rebellion among the Elves. The jewels’ history connects the First Age of Middle-earth with Valinor and the Valar.
The Silmarils are different from the Rings of Power, which were forged much later by Elves and Sauron. They are also distinct from the Arkenstone, a precious stone found beneath the Lonely Mountain in The Hobbit. Tolkien’s mythology presents the Silmarils as unique creations rather than members of a larger ring or jewel collection.
