The State Crown of Mary of Modena is the consort crown made in 1685 for Mary of Modena, queen of England, Scotland and Ireland. It was used by future queens, even by queens regnant until the end of the 18th century.
Originally set with hired diamonds, the crown is set with crystals for display in the Jewel House at the Tower of London.
Mary also had a diadem, also in the Jewel House, and a coronation crown, now owned by the Museum of London.
