Carcanet or carcan is a jeweled collar or necklace, from the old French, carcan, meaning collar. Carcanets were typically quite elaborate and formal, and worn closely fitted. The style seems to have first appeared with the reemergence of the necklace during the end of the medieval period in the late 1300s.
