The items in the Koninklijk Huisarchief are privately owned (okay, legally placed in a legal entity, a Foundation), strange that the sunburst diadem, and maybe other jewels are not kept in one place.
Anyway, it is still at the disposal of the royal family, so let's hope it will be restored and worn again.
--Previous Message-- : I think the reason for that could be that this : item is kept in the Royal Archives : Museum(Koninklijk Huisarchief) which : ofcourse is not the place where the other : jewelery-items of the family are kept. : : : --Previous Message-- : : Remarkable that they never remounted this : piece, nor used the large sunbursts as : brooches. Sure would make a lovely addition : to the collection. : :
