Crown of St. Stephen used to crown Hungarian Kings
A coronation crown is a crown used by a monarch when being crowned. In some monarchies, monarchs have or had a number of crowns for different occasions, such as a coronation crown for the moment of coronation and a state crown for general usage in state ceremonial.
St. Edward's Crown - traditional English then British coronation crown. The current St. Edward's Crown has been used a number of coronations since the restoration of the monarchy in 1660, but not, in fact the majority. The monarchs crowned with St. Edward's Crown were Charles II (1661), James II (1685), William III (1689), George V (1911), George VI (1937) and Elizabeth II (1953). King Edward VII intended to be crowned with St. Edward's Crown but in the event used instead the lighter Imperial State Crown (St Edward's Crown being judged too heavy for the King to wear soon after his illness).
