A Glimpse into Unparalleled Radiance: Sotheby's Premier Jewelry Event

The Star Attraction: A Magnificent Blue Diamond

Headlining the highly anticipated High Jewelry sale at Sotheby's in New York is an unmounted fancy intense blue diamond weighing 10.02 carats. This extraordinary gemstone is expected to realize more than $6 million, marking a rare appearance as only the third fancy intense blue diamond of 10 carats or more to be offered at auction since 2008.

A Spectrum of Rare Colored Diamonds

Beyond the leading blue diamond, the auction presents a dazzling assortment of other high-carat colored diamonds, each estimated to fetch at least $1 million. Among these are a 13.77-carat fancy light purplish-pink diamond, a 6.76-carat fancy grayish-blue cushion-cut stone encircled by pink diamonds, a 5.02-carat oval fancy intense pink diamond with light pink side stones, and a 4.19-carat fancy purple-pink oval diamond featuring round diamond accents on the band.

The Harry Winston Necklace: A Design Masterpiece

The cover lot of the sale is a remarkable 1960s Harry Winston diamond necklace. This piece stands out for its unusual composition of more than 120 carats, primarily featuring round diamonds in trefoil clusters of marquise diamonds. What makes it even more unique is its convertibility into two bracelets, demonstrating both versatility and exquisite craftsmanship. It carries an estimate of $800,000 to $1.2 million.

De Beers Collaboration: Ethical and Exquisite

Continuing its partnership with De Beers, Sotheby's will offer an 11.33-carat internally flawless old mine-cut diamond (D color, type IIa) with an estimate of $600,000 to $800,000. Additionally, two rings featuring 2.01-carat pear-shape diamonds will be part of the sale, with a portion of their proceeds benefiting the Peace Parks Foundation, a conservation charity co-founded by Nelson Mandela.

Paraiba Tourmalines and Historical Gems

Further enriching the auction are five Paraiba tourmalines, ranging from 6.11 to 8.48 carats, sourced from a private collection. These vibrant stones, with the most expensive one estimated at $350,000 to $550,000, are offered individually, except for one pair. The auction also includes a historically significant René Lalique diamond necklace from the 1890s, believed to have been a wedding gift from J.P. Morgan to Elizabeth Sarah Morgan Jay.
