Amazing, but makes me only more curious about what we have not seen yet or could be (like) new again with some adaptations. Anyway what i have missed so far is the top of the queen Emma tiara, with pearls and diamond stars. Someone here or another board said it still was intact only with a wire frame or so.
And yes you are right, complete sets would be very very nice. Maxima choses often to wear not a necklace together with other important pieces.
