Unlikely as Louise of the Netherlands left her jewels to her only daughter Lovisa who married Frederick VIII of Denmark.

Lovisa had a lot of jewels as she inherited half of the jewels of her maternal grandmother Louise of Prussia and also received the Ruby parure of her paternal grandmother who stated that the Danish colors should go to Denmark. Accounts vary between a pool table or a card table but she had enough jewels to cover the surface completely.

The two most important sets remained in Denmark (the pearl set and the ruby set) but I don't see how part of her collection would have gone to Gustav VI Adolf. Her daughter Ingeborg took some jewels but she divided her jewels among her descendants in Norway, Belgium, Luxemburg and Denmark.
