Thanks OmerH and Kongetro. The lower part of the stomacher looks wonderful in the formal portrait. I don't think I had ever noticed it before. And it is interesting to see that HM used the brooch on less formal occasions. Thanks Kongetro!
When I hunted through images I have, I noticed that HM wore it when visiting north America in 1959.
I wonder if Queen Mary ever wore the jewel as separate brooches?
Has anyone ever noticed that?
Has anyone got an image of HM wearing the brooch in Norway?
