On 15 december 1960 Dona Fabiola de Mora y Aragón, the fourth daughter of Gonzalo de Mora y Fernández, Riera y del Olmo, 4th Marquess of Casa Riera, 2nd Count of Mora (1887–1957) and his wife, Blanca de Aragón y Carrillo de Albornoz, Barroeta-Aldamar y Elío (1892–1981) married HM King Boudewijn of Belgium.
During the festivities a lot of royal jewels & tiaras were worn!
You can read a lot more on Ademar's wonderfull site:
I'm interested about the brooch worn by HRH Princess Joséphine-Charlotte of Belgium. She wore on her fur toque an interesting diamond & emerald brooch.
This brooch looks amazing the same like the brooch worn by her sister-in-law Queen Paola. Also Queen Fabiola has a emerald & diamond brooch that looks the same.
Could it be that all 3 brooches were from the inheritance of Queen Astrid/Princess Ingeborg??
The brooch from HM Queen Fabiola. Thankx to Gert-Jan.
