NEW YORK – Sotheby’s first jewelry auction of the autumn auction season will be held in New York on 24 September 2013, with a public exhibition beginning 20 September in Sotheby’s York Avenue galleries.

Gary Schuler, Director of Sotheby’s Jewelry department in New York, said: “The strength of our September sale lies in the remarkable breadth of property that is fresh-to-the-market, emerging from both estates and private collections. We are delighted to offer jewels from the collection of Alex & Elisabeth Lewyt, featuring custom-designed and period pieces by French jewelers such as Schlumberger, Suzanne Belperron and René Boivin. We also have pieces from the family of philanthropist George Rothman, whose collection is led by a beautiful 19.51 carat emerald-cut diamond ring from Harry Winston. This diamond – one of several important white diamonds on offer by private sellers this September – is the caliber of stone that is sure to generate early excitement in the global jewelry market this auction season.”

AUCTION HIGHLIGHTS

Following Sotheby’s spring sales of important Impressionist, Modern and Contemporary art from the collection of Alex & Elisabeth Lewyt, the September auction will offer a selection of jewels from the collection by French designers including Van Cleef & Arpels, Schlumberger and Suzanne Belperron. The group also showcases the abstracted naturalistic designs of René Boivin, highlighted by a fully articulated Labrador Retriever brooch that is both charming and sophisticated.
