A complete copper-alloy Roman plate brooch of c. 2nd century AD date. The brooch is broadly circular, though slightly angular, with sides that tend towards being straight between four lobed knops located one at each cardinal point. The brooch is decorated with three concentric circular grooves, divided by circles of the same height as the circumference. Probable traces of enamel are apparent within the grooves, as with the lobed knops which are each recessed, but not enough survives to be able to reconstruct a colour scheme. Two of the knops have been abraded through externally.

On the flat reverse is a double D-shaped pin lug at the junction of one of the knops and the plate. This retains a small separate copper-alloy axis bar around which a pin with expanded flat head, and general circular cross-section. The pin has been bent to one side and suffered a number of other bends giving it a wavy quality towards the tip. A sub-rectangular catch-plate survives well opposite, over a similar junction of knop and plate.

The brooch now has a brown surface colour. It measures 29.5 by 27.6 by 2.1mm, and weighs 4.97g. The most similar example traced can be found illustrated in Hattatt (2000, 346; no. 1571).
