Her Royal Highness also revealed the great responsibility she and her family have when it comes to wearing and looking after such expensive jewellery. 

After wearing an item from the collection, the Crown Princess is said to personally inspect whether all the diamonds and gems are still in place.

The Royal Court also has a jeweller who is responsible for the reparations and check-ups of these jewels.

As for their favourite pieces from the collection, Queen Silvia favours the Leuchtenberg Sapphire Tiara and the accompanying parure.
