St. Edwards Crown has been removed from the Tower of London to be resized ahead of the May 6 coronation of King Charles III.
The centerpiece of the crown jewels, St. Edwards Crown was commissioned for the coronation of Charles II in 1661.
It replaced the medieval crown that was destroyed in 1649, when Charles I was executed.
The original is believed to date back to Edward the Confessor, the last Anglo-Saxon king, in the eleventh century.
The modern crown is not an exact replica, but similar, with a solid gold frame, rubies, amethysts, sapphires, garnet, topazes, tourmalines and a velvet cap.
The coronation ceremony, conducted by the Archbishop of Canterbury at Westminster Abbey, has remained largely the same for nearly a thousand years, according to the royal family.
