A Noldorin elf, the only son of Curufin, and the only grandson of Fëanor. His name meant 'Hand of Silver' or 'Silver fist'.

Celebrimbor initially lived in Nargothrond but later moved to Eregion, near Moria. There, he had the greatest skill among all the Gwaith-i-Mírdain ('People of the Jewelsmiths' in Sindarin). He drew the letters on the gates of Moria and he made the Elessar the the request of Galadriel (whom it seems he loved).

He also forged many rings, some with Sauron's help (the Nine Rings and the Seven Rings) but his last three Elven-Rings (Narya, Nenya and Vilya), and were made solely by the elves.

Celebrimbor eventually recognized Sauron for what he was, and asked counsel from Galadriel. They decided the three rings should be hidden, and then he gave Nenya to Galadriel. He entrusted Narya and Vilya to Gil-galad.

Sauron started a war to regain these rings, and attacked Eregion. There Celebrimbor was captured, and Sauron found the Nine Rings. He then tortured Celebrimbor to find out where the Seven and the Three were. Celebrimbor told him where the Seven were, because they had been made with Sauron's help. He said nothing about the Three, and was eventually put to death.
