Diamond Diadem

The Diamond Diadem, historically known as the George IV State Diadem, is a diadem that was made in 1820 for King George IV. The diadem has been worn by queens regnant and queens consort in procession to coronations and State Openings of Parliament. It has been featured in paintings and on stamps and currency.
The diadem was most recently worn by Queen Camilla at the 2024 State Opening of Parliament.
==Origin==
George IV commissioned Rundell & Bridge to make the diadem in 1820 at a cost of £8,216. The fee included a hire charge of £800 for the diamonds but there is no evidence they were ever returned to the jewellers. George IV wore the diadem over his velvet cap of maintenance in the procession to his coronation at Westminster Abbey. These are the equivalent of £ and £ in , respectively.
==Description==
The gold and silver frame, measuring tall and in diameter, is decorated with 1,333 diamonds weighing a total of 320 carats (64 g), including a four-carat yellow diamond in the front cross pattée. Along the base are two strings of pearls. Originally, the upper string had 86 pearls and the lower 94, but they were changed to 81 and 88 in 1902. Instead of the heraldic fleurs-de-lis usually seen on British crowns, the diadem has four bouquets of roses, thistles and shamrocks, the floral symbols of England, Scotland and Ireland respectively, alternating with four crosses pattée around the top of its base.
==Use==
It has been worn by every queen regnant and queen consort from Queen Adelaide, the wife of King William IV, to Queen Camilla, the wife of King Charles III. The diadem may have been reset with jewels from the royal collection for Queen Victoria, although the Royal Collection Trust suggests the original 1820 stones were discreetly purchased from Rundell Bridge and Rundell and remain in situ."Normally the stones would have been returned to Rundells after the coronation, but in this case there is no sign that the delicately worked diamond sprays and crosses, a masterpiece of the new transparent style of setting, have been disturbed. Equally, there is no evidence that the King purchased the stones outright, so it could be that the bill was met by a discreet barter of old stones from George IV's extensive collection." https://www.rct.uk/collection/31702/the-diamond-diadem Queen Elizabeth II wore the diadem in the procession to her coronation in 1953, and she also wore it in the procession to and from the annual State Opening of Parliament.
