I apologize if this has been asked previously.

I recently read King George V's biography. There's a quote from Queen Mary relating to their first opening of parliament where she says "What I enjoyed most was wearing grandmama's crown".

At first I thought she was referring to QV's small diamond crown. But when looking at pictures of the event, I realized she was referring to the regal circlet. (Or was it really QV's State Crown without the arches?)

Here's my question: Has anyone worn QV's small diamond crown after Queen Alexandra? When did it get sent to The Tower with the rest of the regalia?
