Borrowed Jewellery? Butterfly Brooch

At the banquet during the state visit to Denmark (March 2017), queen Mathilde wore this diamond brooch in the shape of a butterfly.

It was purchased at auction from Drouot's (Paris) in October 2014, for 8.400 euros by French jeweller Martin du Daffoy, who can by found at the Place Vendôme in Paris.

The brooch was made around 1900. It was described as follows in the catalogue:

Importante BROCHE DE CORSAGE en platine (900 millièmes) et or gris (750 millièmes) ajouré serti de diamants taille ancienne de forme coussin dont sept plus importants, et de diamants taillés en rose, à motifs de volutes, rinceaux et fleurs stylisées. Vers 1900. Dim.: 8 x 5,5 cm. Poids brut: 33,4 g

Even though Martin du Daffoy stated de brooch is still in their possession, Mathilde was again seen with this same model in October 2017, at the cremation ceremony of the late king Bhumibol of Thailand.

And in July 2018, at the Australian state visit to Belgium.
