Boni de Castellane‘s wealthy American wife was one of the legendary collectors. “In 1909, Anna Gould had this necklace made at Cartier, probably from her own diamonds,” explains Marie-Laurence Tixier, director of jewelry department at Christie’s Paris. “And there had to be a large number of them to produce this magnificent matching fall.” The value of this necklace is also due to the extreme delicacy of its mount, which is produced with platinum thread and tassels that extend to the back of the piece.

Estimated at between € 500-700,000 – Auction sale on June 6^th 2017 at Christie’s Paris.
