I thought George V was crowned with St. Edward's Crown as well, however the various depictions of the actual coornation I have seen, notably Tuxen's painting, show him enthroned, receiving homage wearing the Imperial State Crown (and all the golden robes: supertunica, stole and mantle).

My query is that, why would he be wearing the Imperial State Crown when receiving homage, when it should only be worn when processing from the abbey? The change from the coronation robes to the Imperial Purple Mantle and Imperial State Crown in St. Edward's Chapel, happens at the very end of the ceremony.

As such, I query whether or not St. Edward's Crown was actually used, the only monarchs we have pictorial proof of them wearing it are George VI and Queen Elizabeth II.



Interestingly, this Tuxen painting shows HRH The Duke of Connaught taking his place in the front of the Peers. Beyond the Prince of Wales, paying homage, in 1911 were there any other Royal Dukes / Princes of the Blood Royal, eligible to take this position? George V had no survive brothers, his younger sons were not made Peers, and all but one of his uncles had passed.

Note: As you can see in this picture, George VI wears St. Edward's Crown as he receives homage.
