IMPORTANT DIAMONDS & EXCEPTIONAL COLORED STONES Gary Schuler, Co-Chairman of Sotheby’s Jewelry Division, North & South America, said: “As there are no more Kashmir sapphires yet to be recovered from a mine, the only way to present an exceptional Kashmir at auction is when one emerges from a great collection. To have the opportunity to present to the world a sugarloaf cabochon Kashmir sapphire of such size, quality and distinguished provenance as the Ryan family sapphire is truly a privilege. This December we are also fortunate to have several important white diamonds from private collections, each of top quality and possessing both unique characteristics and inherent beauty.” Following the record-breaking sale of the Jewel of Kashmir for $242,145 per-carat at Sotheby’s Hong Kong in October, the December sale will offer an Exceptional Platinum, Kashmir Sapphire and Diamond Ring (estimate $3.5/4.5 million), set with a sugarloaf cabochon sapphire of 25.87 carats, and with no indications of heating. This Kashmir sapphire hails from three generations of one of America’s most prominent families: that of Thomas Fortune Ryan (1851-1928), who stands alongside J.P. Morgan, Andrew Carnegie and John D. Rockefeller in the annals of American financial history. The selection of impressive top-quality diamond rings from private collections includes the Magnificent Platinum and Diamond Ring (estimate $3.5/4.5 million), set with a square emerald- cut diamond weighing 38.27 carats, D color, VVS2 clarity and type IIA – on offer from the Estate of an Italian Countess sold to benefit her charitable founda- tion – and the Very Fine Platinum, Fancy Pink Diamond and Diamond Ring (estimate $2.5/3.5 million), set with a pear-shape stone of 6.93 carats, VS1 clarity, the Property of a Lady. The Highly Important Pair of Emerald and Diamond Earrings (estimate $1.8/2.2 million) are set with Classic Colombian emeralds. Known as The Stars of Muzo, the impressive emeralds weighing 22.97 and 21.37 carats are accompanied by two gemological reports stating the stones are unenhanced. These exceptionally rare emeralds are accented by more than 5 carats of D color, Internally Flawless diamonds. An Important Pair of Platinum, Diamond and Sapphire Earrings (estimate $1,650/ 1,850,000) are designed with cushion-cut diamonds weighing 29.39 and 28.03 carats, both L color and VS2 clarity, set on the bias for a sophisticated contemporary look. JEWELS BY RENOWNED DESIGN HOUSES An extensive collection of Bulgari jewels from the estate of philanthropist and arts patron Adele G. Bergreen coincides with the showcase of Bulgari’s heritage collection in New York. The Bergreen estate includes examples of Bulgari’s most celebrated designs of the 1960s and 70s, including gold link chains, coin jewels, ‘Serpenti’ designs and colorful evening-wear. The highlight of the Bergreen estate is a Platinum, Fancy Colored Diamond and Diamond Brooch, Bulgari, 1964, which features a Fancy Intense Blue diamond weighing 2.47 carats (estimate $500/700,000). Collectors will discover two ‘Drape’ Bracelets by Schlumberger, one lapis lazuli, turquoise and colored diamond, the other coral and diamond, (estimates $20/30,000 each) formerly from the collection of Mrs. Paul Mellon. Mrs. Mellon was known to be a patron of Jean Schlumberger’s jewels and much of her Schlumberger jewelry collection was bequeathed to The Virginia Museum of Fine Arts last year. The spectrum of signed jewels in the sale ranges from late- 19th century pieces to modern designs. One of the most elegant necklaces to be offered is an Exquisite Silver- Topped Gold and Diamond Necklace, René Lalique for Lacloche Frères, Paris, circa 1890 (estimate $750/850,000). Composed of 13 entwined ribbon-style links of graduated design and set with approximately 72 carats of diamonds, this necklace is notable as the only collaboration between Lalique and Lacloche known to still exist. A century later, JAR created a Pair of Silver, Gold, Topaz and Diamond ‘Feather’ Earclips (estimate $250/350,000). These earclips were included in the Metropolitan Museum of Art’s exhibition Jewels by JAR in 2013-2014. For more information visit : www.sothebys.com
