There's something I've been thinking of: Silvia often lend Victoria and Madeleine her tiaras. Here in Denmark the collection is only for the reigning queen to wear, and then there is the ruby tiara for the crownprincess. Is that because the swedish jewels are the family's personal properties or what? It's a pity Silvias jewels not are on display, I've would have loved to them in real life.
The reason could be that the Swedish private collection is far bigger than the Danish.
I've got an article from Svensk Damtidning; it doesn't say which tiaras
belong to the crown jewels and which are private, but there are plenty to choose
from and and pass around!
The Danes are paupers in comparison!
Princess Alexandra only had one tiara, the diamond drop tiara (of queen Alexandrine), and
apart from the ruby tiara, which is not very versatile, CP Mary is left with the diamond tiara
HM and Prince Henrik gave her as a wedding gift.
