§ Of the Ruin of Doriath The Silmarillion

Now Húrin journeyed eastward, and he came to the Meres of Twilight above the Falls of Sirion; and there he was taken by the Elves that guarded the western marches of Doriath, and brought before King Thingol in the Thousand Caves. Then Thingol was filled with wonder and grief when he looked on him, and knew that grim and aged man for Húrin Thalion, the captive of Morgoth; but he greeted him fairly and showed him honour. Húrin made no answer to the King, but drew forth from beneath his cloak that one thing which he had taken with him out of Nargothrond; and that was no lesser treasure than the Nauglamír, the Necklace of the Dwarves, that was made for Finrod Felagund long years before by the craftsmen of Nogrod and Belegost, most famed of all their works in the Elder Days, and prized by Finrod while he lived above all the treasures of Nargothrond. And Húrin cast it at the feet of Thingol with wild and bitter words.
