Below are two more images which Maridje kindly sent to me. (The one I used on the banner shows only the part of the bandeau which can be worn as a bracelet)
Thank you so much Maridje!!
I have only ever seen Edwina Mountbatten photographed wearing the jewel as a bracelet,
although there are press reports of her having worn the bandeau to society functions.
At the Cartier Exhibition in Canberra in 2018 the bandeau was in a free standing display cabinet which enabled us all to walk around the jewel and see how the joining mechanism works.
And on the opposite side
A closer view of the box clasp section.
My understanding is that the bandeau is now in the V & A, but I cannot find it on the website.
Does anyone know if it is indeed part of the V & A's collection?
