Personally I find a head of state, seated on a golden throne, wearing ermine fur while balancing a wobbling crown with an overload of diamonds extremely out of touch. Imagine Charles in 2030 or William in 2050 with glittering diamonds on their head.
Especially when this pompously dressed head of state, speaking of "My Government", announces draconic cuts or tax hikes while the Cullinan II glitters above their forehead.
No, having the Imperial State Crown on a pedestal as a symbol of the kingship (like the mace in the two Houses of Parliament) suits better with a modern monarchy 3.0, is my personal opinion. In Sweden the ermine was not worn but draped on the throne, that is also an option which would be an improvement in my eyes.
