The George IV State Diadem, officially the Diamond Diadem, is a type of crown that was made in 1820 for King George IV. The diadem is worn by queens and queens consort in procession to coronations and State Openings of Parliament. The piece of jewelry has been featured in paintings and on stamps and currency. It can be seen in the Queen's Gallery at Buckingham Palace.

ELIZABETH II DEI GRATIA REGINA FIDEI DEFENSATRIX means Elizabeth II, by the grace of God, Queen and Defender of the Faith.

Depicts the White Lion of Mortimer standing proudly beside a Yorkist shield dividing date and surrounded by the inscription below.

The White Lion of Mortimer descends to the Queen through Edward IV. The shield shows a white rose encircled by a golden sun, known heraldically as a ‘white rose en soleil’ which is really a combination of two distinct badges. Both of these appear on the Great Seals of Edward IV and Richard III, and were used by George VI when Duke of York. This beast is usually shown sitting with its tail between its legs, characterising traits of loyalty and discipline. Unlike the Lion of England, the White Lion is uncrowned, and its tongue and claws are blue as opposed to red.

Anne Mortimer (1388–1411) was a medieval English noblewoman who became an ancestress to the royal House of York, one of the parties in the fifteenth-century dynastic Wars of the Roses. It was her line of descent which gave the Yorkist dynasty its claim to the throne. Anne was the mother of Richard, Duke of York, and thus grandmother of kings Edward IV and Richard III.
