The DoE also designed a bracelet for HM for an occasion early in their marriage -- perhaps his wedding gift to her. I can't remember who executed the design, nor can I remember anything other than it was yellow gold with gemstones. Anyone have a photo?
Update: Boucheron made a gold, sapphire, diamond and ruby bracelet made by Boucheron to Prince Philip’s design. It was given to The Queen on their fifth wedding anniversary and incorporates the interlaced initials ‘E’ and ‘P’. I'm still unable to find a photo.
