Further down a very interesting conversation is taking place about bejewelled fans and their history. Unfortunately I know next to nothing about this subject. However the only Royal lady I can think of who has carried a fan in recent times is Queen Maxima at 2 Swedish weddings. Wonder if they are old jewelled fans but unfortunately no good pics are available for confirmation.
These look like modern cheap paper fans, not jewlled fans. The only royal in modern times I can recall to be photographed with good quality old fans is Queen Elizabeth II between the 1950s-1970s and then she was using her grandmother Queen Mary's fans and they were only being used for formal portraits.
Good quality fans show equal quality workmanship in both the sticks, guards and leaf and the best of them are planned before they are made with the whole harmonizing.
