The last wearer of the amethyst set seems to have been Jeanne Linnie Alice Clifford Kocq van Breugel née Baroness van Nagell (1918-2007). Her husband died last year: Jonkheer
Willem François Clifford Kocq van Breugel (1914-2015).
Some googling learned that the Baroness was the last person with the surname Van Nagell. The couple lived at Schaffelaar Estate (picture
). During her life the Baroness sold the building for 1 guilder to the municipality of Barneveld. The domain around was donated to the Foundation Guelders' Landscape.
After the death of the husband in 2015, the children donated artworks to several institutions. It would have been nice when the set was offered for sale to the royal family. Maybe this exhibition brings the King (Executive of the Foundation Crown Properties of the House Orange-Nassau) to make a purchase. This year it is 200 years ago that Anna Paulovna Romanova became Princess of Orange. It is a very historic piece and the Dutch collection lacks big eyepopping amethysts. What more reason does the Foundation need?
When the King can purchase villas, speedboats, breath-takingly expensive cars and order the Golden State Coach (and before that the Glass State Berline and the Crême Calèche) to be painfully restored against mega-amounts, he can purchase a set of jewels too.
