The Silmarils (originally called Silmarilli in Quenya), also known as the Jewels of Fëanor, were a set of three gems crafted by Fëanor from essence of the Two Trees of Valinor, Laurelin and Telperion, before the First Age. They were among the most prized of all the wonders crafted by the Elves and were coveted by many. It was said that the fate of Arda was woven about the Silmarils
