This gold and enamel brooch bearing the cypher of Queen Mary II comes in a fitted case by Plante, 12 Bury Street, London. By repute it was given to Miss Jean Harkness, a personal housemaid to the queen.
Offered together with a signed photograph of Queen Mary, it carries an estimate of £200-400 at Sworders of Stansted Mountfitchet on July 11.
