Revyn Sadri's Copper and Onyx Circlet is a unique circlet in The Elder Scrolls V: Skyrim. It can be bought from Revyn Sadri. The circlet counts as a helmet when worn; it offers 0 damage resistance, but can be enchanted. Sadri's Circlet is exactly the same as the Copper and Onyx Circlet, except for value. It is not associated with any quests.

As with all circlets, Copper and Onyx Circlets can be worn with a Falmer Helmet, but not the Falmer Hardened Helm. It can also be used with a Penitus Oculatus Helmet, or a Dragon Priest Mask.
