The point at issue was the extent to which the King, far more than his father, the more flamboyant, socialising and widely travelled King Edward VII, was responsible for developing the outward ceremonial of the monarchy, and expecially in the first four years of his reign between 1910 and 1914.
Instead of hiring in precious stones for the occasion to decorate crown it was permanently set with precious and semi-precious stones and displayed with them ever since.

Notwithstanding the difficulties of wearing a crown upon his return and from 1913 until his death, the King, unlike his father, actually wore the Imperial State Crown at the annual State Opening of Parliament
As David Starkey points out in his history of the monarchy this necessiated various adjustments over the years to the frame to try and make the crown more comfortable for the monarch to wear.
There appears to be a clear pattern in all this, and it must be one that was coming from the King himself and circle around him - carring further what his father had done - not quite what might expect from a King often thought to be rather diffident - certainly at this point in his reign with the major constitutional issues of the House of Lords and Irish Home Rule so prominent. They can be seen as balancing the regional tours the King and Queen carried out in those pre-war years.
Writing in exile in the early 1920s the king's cousin, Emperor Wilhelm II commented with reference to the ceremonial around the unveiling just before the Coronation in June 1911 by the two monarchs of the Queen Victoria Memorial that monarchies with less direct power were, the Kaiser thought, more inclined to the use of public spectacle and ceremony. That is an interesting insight from an insider - though few modern monarchs have been as keen on outward ceremony as Wilhelm, and he, presumably, was implying he had more direct power than his cousin George.
That this concern for historic ceremonial was not just a pre-War mood can be seen in the revival by King George V of the monarch's personal participation in the Royal Maundyservice in the early 1930s, at the suggestion of his cousin Princess Marie Louise.
