A medieval annular brooch made from copper-alloy. The frame is divided along the axis of the pin with two different designs: one half has a square cross-section that is twisted; the outer faces are engraved with wriggle work. The other half has a slightly angular cross-section that does not twist; at ninety degrees to the pin is a bulbous cylinder incised with cross hatching. The frame has a constriction for the pin. The pin is missing.
