I do wonder to what extend Maxima herself goes rummaging through all the boxes and decides to send a long lost piece to the Court Jeweller for a check up and cleaning or is it a courtier or the jeweller who goes through the inventory, if there is one, and who suggests it to the Queen.... I am saying this because it was well known that Beatrix had little interest and was less aware of the full extend of the collection and the potential of all the individual pieces.
