The Noldor were the "deep Elves", always interested in knowledge, skill, and understanding. King Finwë of the Noldor had two wives. His first was Míriel; she was the most skilful of the Noldor in needlework and weaving. Míriel gave birth to their only child, Curufinwë, commonly called Fëanor; he inherited her skill, becoming the most gifted and brilliant of all the Noldor, the mightiest in crafts, especially the making of jewels. He makes the Silmarils, which cause strife among Elves, Men, and Dwarves, stirred up by the first Dark Lord Melkor, as told in "The Silmarillion". Fëanor's grandson Celebrimbor makes Rings of Power, which cause further strife, as told in "The Lord of the Rings".
