The Silmarils (Quenya pl. Silmarilli, radiance of pure light) are three fictional brilliant jewels composed of the unmarred light of the Two Trees in J. R. R. Tolkien's legendarium. The Silmarils were made out of the crystalline substance silima by Fëanor, a Noldorin Elf, in Valinor during the Years of the Trees. The Silmarils play a central role in Tolkien's book The Silmarillion, which tells of the creation of Eä (the Universe) and the beginning of Elves, Men, and Dwarves.
