Mike's recent comment about the Cartier Exhibition prompted me to download some more photos I took.

Below is the Mountbatten tutti frutti bandeau, purchased from Cartier, London, in 1928.



The bandeau can be divided into 2 bracelets.

The photo below shows where one of the joins is located.



I have never seen an image of Edwina Mountbatten wearing the jewel as a bandeau; however, there are photos of her wearing it as a bracelet.



Today the tiara is owned by the Bollingers who lend it to the V & A. Apparently the first time the jewel was allowed to leave the UK (after it was sold) was for the 2018 Cartier Exhibition.
