Sorry everyone, I slightly misunderstood, I thought you said the top "brooch" was the Star of the Order of Aftab, which it is not but it does look like a portrait in a diamond frame, which for the occasion would be most likely The Shah. (I didn`t realize QV had a miniature portrait of the Shah) Anyway I expect the "Star of the Order" would not be worn on the neck. QV is probably wearing the sash badge but it doesn`t show in the photo. It is quite a spectacular Order, Queen Alexandra`s had 3 diamond drops on her version. : :
