Going through images of the late Duchess and looking for information on her jewellery I came across a brooch that she seems to have worn quite regularly early in her marriage. At least I think it is the same brooch. The one I am thinking of was worn by the late Duchess for the official photographs released with her newborn daughter Lady Helen in 1964 (the first photo below). But then looking even further back she seems to have worn the same brooch for the official photographs released with her firstborn as well (second photo). Would you say that this is the same brooch?
