No Dutch royal owns major jewels or possessions

I think that's right, I don't think that she really owns a tiara because most of the tiaras & jewels were put once in a foundation. But as Auntie said, she can use these jewels when she needs them.
If you compare it with HRH Princess Claire, ... Claire has her own tiara... Maxima hasn't a tiara of her own but can wear the whole collection.
Queen Wilhelmina (1880-1962) and her daughter Queen Juliana (1909-2004) were single children and the single heiresses of all the Orange-Nassau fortunes and possessions.
This was an unique and never seen situation: all the jewels, the artworks, the properties, the archives, the libraries, the estates, for an exceptional long time in ownership of one single person.
Because Netherlands civic law requires that the surviving spouse and all children have the right on specific equal parts of the heritage, this would mean a break up into 4 children and their 14 children and their .... children.
To avoid the prizeless collections to be broken up and sold off, Queen Juliana has put almost everything into the ownership of various family-foundations like the Foundation Historic Collections of the House of Orange-Nassau, the Foundation Archives of the House of Orange-Nassau, the Foundation Crown Properties of the House of Orange-Nassau, etc.
Of course the princesses do have personal jewelry, for an example parts of the huge 1901 Diamond Wedding Gift Parure, but the main jewels, the gold-, silver- and crystalware, the artworks, the carriages, the inventory of the many palaces, etc. are no longer in personal ownership.
However this was a difficult step to take (you give away family properties in trusts), the advantage is that for eternity the wonderful collections will remain together, so that also Queen Catharina-Amalia will be able to eat from golden plates once used by Mary II Stuart. That also Countess Eloïse can ride to her wedding church in a carriage which once transported Queen Anna Paulovna. That Princess Máxima can wear the House Diamonds which once dazzled Napoleon's contemporaries.
