Wow. What an amazing discovery! Thank you so much Pedro. The tiara seems to be an art deco jewel and the necklace is, at least for me at a first sight, a 2 or 3 rows diamond rivière. As you, I do not have informations about those jewels but I suspect they are, nowadays, in the Duke of Braganza vault. Because D.Duarte inherited the well known brooch that is worn nowadays by the Duchess and a beautiful mansion in the Algarve, I always had the feeling that HRH (as the Head of the Royal House of Portugal) was favored in D.Filipa will. Maybe we will see those jewels one day, worn by HH D.Maria Francisca, by a future Duchess of Porto or, even better, by a future Princess of Beira.
