I just posted a piece on the State Visit on my blog where I have tried to make a list of all the grander jewels worn to both evening events:

Lately it seems like at least the younger generation has developed what looks like an allergy to necklaces, but at the return dinner hosted by the Egyptian president Princess Marie was seen wearing an interesting necklace. I cannot remember having seen this one before. Is it new and is it real diamonds I wonder?
