Mary of Modena's Diadem
1685RCIN 31708
This diadem was ordered only six weeks before the coronation of James II and his wife Mary in 1685, and was delivered the day before the ceremony. It was originally encrusted with 177 diamonds which were provided on loan, but these have been replaced by quartz crystal. Mary of Modena's step-daughter, Mary II, wore the diadem in 1689 and it was again worn by Queen Anne in 1702.
