One of my favorite lots in the sale is a lovely Belle Époque diamond longchain necklace comprising 257 collet-set old European-cut diamonds circa 1910 (est. $40,000-50,000). With an estimated total diamond weight of 53.60 carats, the flowing stream of diamonds a splendid example of the long necklaces fashionable at the time, often layered and draped in abundance around one’s neck. This particular chain was a gift from renowned German novelist Thomas Mann, the recipient of the 1929 Nobel Prize for Literature, to his wife. It has remained within the Mann family ever since.

Footnotes

Based on the unusual color palette and the design, one would assume this necklace was created by Louis Comfort Tiffany’s head designer Meta Overbeck between 1915-1920. Her creations exemplify a clear understanding of jewelry, color and balance.

It is likely that this sautoir was the culmination of three distinct creative forces at Tiffany & Company, responsible for the outstanding designs during this era. First with George Kunz, the head gemologist for Tiffany & Co. possibly procuring these beautiful and lively coffin-shaped aquamarines, presenting them to Louis Comfort Tiffany. Tiffany would then suggest that these gemstones be incorporated into a Moorish inspired design. Lastly, Meta Overbeck would be entrusted to create designs that transposed these ideas into a piece of jewelry.

The pattern of this necklace together with its color palate of fancy- cut gemstones reflects the classic texture seen in Moroccan architecture and is echoed in the intricately designed gold gallery. This theme was present in many of Louis Comfort Tiffany’s creations as well as seen in his home at Laurelton Hall.
