The fifth crowned portrait of HM Queen Elizabeth II facing right, wearing the George IV State Diadem and drop earrings.

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.

A dynamic depiction of the Falcon of the Plantagenets leaping over the shield shows the Falcon and Fetterlock Badge of Edward IV.

The falcon was first used by Edward III of the House of Plantagenet as his badge. It descended to Edward IV, who took it as his personal badge, the falcon being standing within an open fetterlock. The white Falcon at The Queen’s coronation held a shield with a badge depicting a second white falcon within an open golden ‘fetterlock’ or padlock.

The fetterlock and the falcon were popular emblems in the Houses of both York and Lancaster, as they had descended from Edward III’s younger sons John of Gaunt and Edmund of Langley. The fetterlocks used by John and Edmund were always locked, perhaps to show they had no claim to the throne. Edward IV gave his younger son, Richard, the badge of a white falcon within an open fetterlock – the lock Edward forced to take the throne. Henry VII, who united the houses of York and Lancaster with his marriage to Elizabeth of York, often used a falcon symbol and it was said to be the favourite badge of Queen Elizabeth I.

The House of Plantagenet was a royal house which originated from the lands of Anjou in France. The family held the English throne from 1154, with the accession of Henry II, until 1485, when Richard III died in battle.
