A type of torc that is in the form of a complete hoop rather than the usual penannular ring, having a detachable segment that is about one-sixth toone-eighth of the total circumference and that is attached to the larger portion by mortise-and tenon joints. Such torcs, made of bronze, and sometimes decorated in Waldalgesheim style, have beenfound only in Champagne, France, and were worn there by high-ranking women; they are of the Early La Tène century, c. 4th century BC.
