Anne Boleyn was crowned with the crown of St Edward, which had previously only been used for crowning the reigning monarch and after the Te Deum was sung and she was able to swap the heavy St Edward’s crown for a specially designed lighter one.
The original St Edward Crown was destroyed in the English Civil War but was recreated for the coronation of Charles II in 1661. You can find out more about it if you do a search on Wikipedia for "St Edward's Crown" and also on the Wikipedia page for "Crown Jewels of the United Kingdom".
