Circular gold disc with vertical sides on which are attached three loops. The backing is now missing. The face is ornamented with a beaded wire edge inside which are concentric bands of plain wire and four torque wires all surrounding a raised cloisonne enamel medallion. This medallion contains a translucent green quatrefoil with an opaque white circular center, and with an opaque white crescent surrounding each lobe, all set in an opaque blue field. Around this is a band in which seed pearls strung on wire alternate with loops of gold, and outside this is a band of enamelled cells made by a meandering gold cloison, the enamel now lacking.
