Thank you for the pictures and the explanation. Finally I understand where the earring came from. The alteration made in the necklace seems to had been quite successful.
I also saw written that these jewels are "not very far from where it should be". But what does it mean exactly?
Nevertheless, for some reason that I cannot fully explain, I think that we may have some very interesting surprises in the future, probably with the new generation of royals in the Portuguese Royal Family.
For a future Princess of Beira, an Infanta and a future Duchess of Porto, it will be needed some jewels to get out from the vaults.
