Enameling shows small areas of damage and loss, but the piece is in respectfully good condition for its age.

The reverse of this cross is an almost identical replica of the Pectorial Cross of the Abbot of Averbode dating from 1562, currently in the Kunstgewerbemuseum in Berlin. 

The coat of arms and mitre belonged to Mathaeus van Rethen who was the Abbot of Averbode at the time the original cross was made. His motto translates as 'Nothing Too Much' ; the text underneath as 'Sir Matthew van Rethan, Abbot of Averbode, decorated me with pure gold and precious stones'.
