I will post a series of images showing some of the jewels QEII wore in Canada in 1957.
The first shows HM at a ceremonial at the War Memorial.
Is HM wearing a maple leaf brooch on her hat?
Could it be the one given to her as a wedding gift by one of the Canadian groups? I am thinking of the one which has a diamond set vein in the middle of the maple leaf -- apologies I don't have a separate photo of this brooch, although I have seen one some where.
What other brooches is she wearing?
