I have unfortunately no information about the origin of this brooch. I do not know if it is a gift from King George VI to his wife, or an element of the Greville bequest, or a personal purchase, or a wedding gift, or a gift from another person, or an earlier heirloom of the Royal Family (I would say the style of the brooch is Victorian, so the brooch could possibly have been in the Royal Family before Queen-Mother Elizabeth)...
Here are the best close-up I have of this lovely spray brooch:
- in Armagh in March 2008 (Maundy service):
- in Berlin last Thursday (unfortunately partially hidden):
I think that this brooch looks better on a dark background, rather than on a white one.
