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.

==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.<ref>{{Royal Collection|31702|The Diamond Diadem}}</ref> These are the equivalent of £{{Inflation|UK-GDP|8216|1820|fmt=c|r=-5}} and £{{Inflation|UK-GDP|800|1820|fmt=c|r=-4}} in {{Inflation-year|UK-GDP}}, respectively.{{Inflation-fn|UK-GDP}} George&nbsp;IV wore the diadem over his velvet cap of maintenance in the procession to his coronation at Westminster Abbey.<ref name="AllisonRiddell1991">{{cite book|author1=Ronald Allison|author2=Sarah Riddell|title=The Royal Encyclopedia|url=https://books.google.com/books?id=kIoUAQAAIAAJ|year=1991|publisher=Macmillan Press|isbn=978-0-333-53810-4|page=173}}</ref>
