Thanks Vincent for your very interesting information. That is a possiblity, because it was the only occasion we saw those jewels on Queen Giovanna.
What is more, despite the jewels that Queen Giovanna owned personally, including several diadems, still she borrowed jewels to wear from her brother's. I am referring to the time she borrowed the Mellerio tiara to wear in Estoril for Infanta Maria del Pilar's wedding in 1967. The photo of this event it is also reproduced on the cover of the book "Reis no Exilio" by HRH Pince Charles-Philippe d'Orléans.
