Sotheby’s Geneva Showcases Exceptional Provenance and Record-Breaking Natural Diamonds

Each November, Geneva takes centre stage in the world of fine jewellery, and Sotheby’s 2025 High Jewellery and Royal & Noble Jewels sales reaffirm why the city remains its beating heart.

Each November, Geneva takes centre stage in the world of fine jewellery, and Sotheby’s 2025 High Jewellery and Royal & Noble Jewels sales reaffirm why the city remains its beating heart. This year’s auctions bring together a breathtaking display of natural diamonds, historical heirlooms, and masterful craftsmanship that celebrate centuries of artistry and provenance.

At the forefront of the Sotheby’s High Jewellery Sale is The Glowing Rose, an extraordinary 10.08-carat Fancy Vivid Pink diamond estimated at around USD 20 million. Its rare, “pure pink” hue—free from secondary tones—places it among the most valuable gemstones in existence. Comparable to celebrated stones such as the Williamson Pink Star and Pink Legacy, this exceptional diamond embodies the geological miracle of atomic distortion, which gives natural pink diamonds their ethereal glow. Stones of this size and purity are exceedingly rare, making The Glowing Rose the undeniable star of the season.

10.08-carat Fancy Vivid Pink diamond

Colour remains the hallmark of this year’s Geneva sale. A pair of Fancy Vivid Yellow diamond earrings, weighing 38.66 and 38.88 carats, are expected to achieve between CHF 2,000,000 and CHF 3,800,000. Their radiant colour intensity and impressive carat weight represent the highest standards of fancy diamond grading. Equally captivating is a 4.50-carat Fancy Vivid Blue diamond, internally flawless and estimated at CHF 4,400,000 to CHF 5,800,000. The blue hue, caused by trace boron, adds to its rarity and appeal, offering collectors the coveted trifecta of exceptional colour, clarity, and size.

Among the coloured gemstones, a 7.69-carat “Royal Blue” Kashmir sapphire set in a ring-pendant combination by Van Cleef & Arpels is a standout. Revered for their velvety “sleepy” lustre, Kashmir sapphires are among the most desirable in the world, and this piece exemplifies the pinnacle of gemological beauty. Further artistry is showcased through a pair of sapphire, tsavorite garnet, and diamond earclips by JAR—vividly imaginative and estimated at CHF 300,000 to CHF 500,000—reflecting the contemporary genius of Joel Arthur Rosenthal.

The sale also includes signature creations by Van Cleef & Arpels, Cartier, Graff, and De Grisogono. Highlights include a 10.04-carat marquise-shaped D-colour diamond ring by Graff (VVS2 clarity, estimated CHF 320,000–560,000) and a De Grisogono ruby and diamond bombé ring featuring two step-cut diamonds (estimated CHF 55,000–75,000).

In tribute to a century of Art Deco design, Sotheby’s presents an array of geometric masterpieces from Cartier and Van Cleef & Arpels, embodying the symmetry and elegance that shaped modern jewellery aesthetics. Two private collections will also headline the event: one dedicated exclusively to Van Cleef & Arpels, and another—Aria of Jewels: The Collection of Antje-Katrin Kühnemann—featuring exceptional Cartier and De Grisogono pieces from the late philanthropist’s private trove.

The Royal & Noble Jewels: A Journey Through History

Complementing the High Jewellery Sale, Sotheby’s Royal & Noble Jewels auction unveils some of the most historically significant diamonds and heirlooms ever offered. Among them is a diamond brooch once owned by Emperor Napoleon Bonaparte, lost during his flight after Waterloo and later recovered by the Prussian Royal family. After more than two centuries in private hands, it now re-emerges for the first time at auction.

Also featured is a light pink diamond ring with royal lineage, once belonging to Empress Catherine I of Russia and later to Princess Neslishah Sultan, estimated between CHF 240,000 and CHF 400,000. A natural pearl and diamond jewel formerly owned by Cunegonde of Saxony (cousin of Louis XVI) carries an estimate of CHF 340,000 to CHF 500,000, while a diamond tiara with a wild roses motif from the Duchess of Portland (1774–1844) is expected to fetch CHF 100,000 to CHF 170,000.

Adding to the grandeur is a Cartier emerald and diamond necklace featuring an 11.78-carat Colombian emerald, commissioned in 1932, exemplifying Art Deco refinement and royal provenance.

Celebrating Provenance, Craftsmanship, and Natural Rarity

From Napoleon’s lost brooch to The Glowing Rose, Sotheby’s Geneva continues to highlight how exceptional gems transcend beauty—they embody heritage, artistry, and history. These November 2025 auctions remind the world that in fine jewellery, rarity, provenance, and craftsmanship remain the ultimate symbols of enduring value.

Napoleon’s Diamond Brooch Leads Sotheby’s Sale

Napoleon's Diamond Brooch

Treasures that once belonged to Napoleon Bonaparte are to be offered for sale by Sotheby’s Geneva on 12 November.

Details of the auction were revealed on Friday (24 October), less than a week after the devastating raid on the Louvre, in which items from the French crown jewels, valued at over $100m, were stolen.

Highlight of the Royal & Noble Jewels Sale is Napoleon’s unique brooch featuring old mine and mazarin-cut diamonds that was pinned to his hat during the 1815 Battle of Waterloo.

At its center is a large oval diamond weighing 13.04 carats, surrounded by nearly 100 old mine-cut diamonds arranged in two concentric rows.

The brooch was seized by the victorious Prussian army as the defeated Napoleon fled.

It appears for the first time at auction with an estimate of CHF 120,000 to 200,000 (USD 150,000 to 250,000).

“In his haste to flee Waterloo, where his armies had been overwhelmed by the combined forces of the British and Prussian armies, Napoleon had to abandon some of his carriages when they got stuck in a muddy road a few miles away from the battlefield – including the carriage containing those precious belongings,” Sotheby’s said.

Three days later the brooch was presented to Prussian King Friedrich Wilhelm III as a battle trophy.

It remained within the House of Hohenzollern for centuries, and passed down to emperors of Germany. It has been part of a different private collection for the last few years.

Unique Patek Philippe Sells for $4.3m

Patek Philippe

A unique Patek Philippe watch sold for $4.3m at Sotheby’s New York – the highest price realized by the auction house for a timepiece this year.

But it was well below the $7.75m achieved by the same watch when it changed hands at Sotheby’s Hong Kong.

The pink gold perpetual calendar chronograph wristwatch with moon phases, was made in 1957 and was sold by the Milan-based retailer Gobbi Milano.

It was one of just nine made and is the only one known to still exist.

A private collector paid $4.3m for the watch, which had a pre-sale estimate of $3m to $5m. It led the Important Watches: Take a Minute sale last Tuesday (10 June).

In 2007 the watch sold for CHF 2.7m ($2,.2m at historic exchange rate) at Christie’s Geneva.

Dazzling Diamonds and Storied Provenance Headline Sotheby’s New York High Jewellery Auction

The Crown Jewel: 35.01ct Graff Diamond Ring

Sotheby’s New York is set to host an extraordinary High Jewellery auction on 13 June, featuring 110 remarkable lots — many of them centred around colourless and fancy coloured diamonds. This exclusive sale not only showcases some of the most important stones on the market today but also brings to light jewellery with historic provenance, including pieces from the Vanderbilt and Wade families, and a private collection chronicling a decades-long romance.

The Crown Jewel: 35.01ct Graff Diamond Ring
Leading the sale is a breathtaking 35.01-carat emerald-cut diamond ring from luxury jeweller Graff. This D-colour, VVS2 clarity diamond is described as “highly important,” and is expected to fetch between USD $2 million and $3 million (approximately AUD $3 million to $4.5 million). It’s one of 13 spectacular jewels from a private collection titled Joie de Vivre: Journey in Jewels — a tribute to a husband’s enduring love, with each piece gifted to his wife throughout a 60-year marriage.

Another standout from the same collection is a pair of emerald and diamond earclips by Graff, boasting four sugarloaf cabochon emeralds weighing a total of approximately 84 carats. These exceptional earrings carry a presale estimate of USD $800,000 – $1.5 million.

Additional highlights from this private collection include:

An aquamarine and diamond bracelet: USD $40,000 – $60,000

A jade and diamond pendant-brooch, circa 1910s: USD $25,000 – $35,000

Fancy Colours Steal the Spotlight
The number two lot of the sale is a striking 5.02-carat fancy pink diamond ring with VS2 clarity, estimated at USD $1.5 million – $2.5 million. Following closely is a 2.02-carat fancy vivid blue diamond ring, cut in a modified rectangular mixed style, with an estimate of USD $1.4 million – $1.8 million.

Also drawing significant attention is a pair of flawless D-colour pear-shaped diamonds weighing 10.32 and 10.11 carats respectively. Both diamonds are rated “excellent” in polish and symmetry, with a combined estimate of USD $1.1 million – $1.5 million.

American Legacy: Vanderbilt and Wade Family Heirlooms
Among the historic highlights is a ruby and diamond sautoir by Marcus & Co., dating back to circa 1915. The centrepiece is a 9.60-carat unheated Burmese ruby, surrounded by old European-cut diamonds and accented with calibre-cut rubies. This important jewel is estimated at USD $1 million – $2 million and once belonged to Emily Vanderbilt Wade, the great-granddaughter of Cornelius Vanderbilt and daughter of Rhode Island Governor William Henry Vanderbilt III.

Three other Vanderbilt Wade jewels will also go under the hammer:

Cartier Art Deco diamond bracelet: Estimated at USD $60,000 – $80,000

Rene Lalique Art Nouveau pendant: Crafted from gold, enamel, emerald and pearl, circa 1900, with an estimate of USD $20,000 – $30,000

Multistone tassel sautoir: Featuring rubies, emeralds, pearls, diamonds and enamel, and possibly designed by Paulding Farnham of Tiffany & Co., with an estimate of USD $40,000 – $60,000

A Rare Opportunity for Collectors and Connoisseurs

Al Capone’s Diamond-Studded Patek Philippe Pocket Watch Heads to Sotheby’s Auction

Al Capone’s Diamond-Encrusted Pocket Watch to Be Auctioned at Sotheby’s

Al Capone’s Diamond-Encrusted Pocket Watch to Be Auctioned at Sotheby’s

A dazzling piece of underworld history is heading to auction: Al Capone’s custom diamond-studded pocket watch, crafted from platinum and set with 90 diamonds, will go under the hammer at Sotheby’s next month. The extraordinary Patek Philippe timepiece, dripping in gangster-era flair and opulence, is expected to fetch between USD $80,000 and $160,000.

Nearly a century before “bust-down” watches became a mainstay in hip-hop culture, Capone was already setting trends. Dissatisfied with the understated design of his factory-made Patek Philippe, the infamous Chicago mob boss commissioned a local jeweller to completely rework it. The result? A solid platinum case housing the original movement, with a striking caseback spelling out “AC” in 90 single-cut diamonds—a bold, custom feature unheard of at the time.

“This type of gem-setting would have been extremely rare during that period,” says Geoff Hess, Sotheby’s Global Head of Watches. “Capone wasn’t just ahead of his time as a criminal—he was ahead of his time in style.”

This is not the first time Capone’s lavish timepiece has appeared at auction. In 2021, it was sold alongside other personal items—including his diamond tie bar and favourite Colt .45 pistol—by his descendants through Witherells, a California-based auction house. Estimated at $25,000 to $50,000, the watch far exceeded expectations, fetching $229,900.

While the dial shows signs of age and the minute hand is missing, the watch remains a compelling piece of Americana. It’s less a horological grail than a conversation-starting symbol of 20th-century notoriety and excess. Today, collectors tend to frown upon aftermarket diamonds, especially in vintage watches—but this piece is a bold exception. Capone’s customised pocket watch stands as a testament to his legacy: extravagant, defiant, and unmistakably iconic.

Rare 10.3-Carat ‘Mediterranean Blue’ Diamond Sells for $21.5 Million at Sotheby’s Geneva Auction

Mediterranean Blue’ Diamond
Mediterranean Blue’ Diamond

A rare 10.3-carat fancy vivid blue diamond, known as The Mediterranean Blue, has sold for an astonishing $21.5 million (17.9 million Swiss Francs) at Sotheby’s High Jewellery Auction in Geneva. This exceptional gemstone not only topped the auction but was also the headline piece of Sotheby’s week-long jewellery sales in Switzerland.

Intense Bidding War Over a Fancy Vivid Blue Diamond
The auction, livestreamed globally, saw a fierce bidding battle that began at 9 million Swiss Francs. Within the first minute, the price surged to 13 million, eventually narrowing to two determined phone bidders. After two and a half minutes of competitive bidding, the final hammer price landed at 15 million Swiss Francs, with additional premiums pushing the total sale price to $21.5 million.

The winning bidder was represented by Frank Everett, Vice Chairman of Jewelry, Americas at Sotheby’s. The blue diamond had been estimated at $20 million prior to the auction.

From Cullinan Mine to Record Sale
The Mediterranean Blue diamond was cut from a 31.94-carat rough blue diamond discovered in 2023 at the legendary Cullinan mine in South Africa, a source renowned for producing some of the world’s most important blue diamonds. Sotheby’s revealed that the rough stone underwent a full year of study before undergoing a meticulous six-month cutting and polishing process to achieve its final cushion modified brilliant-cut form.

Global Tour Boosted Demand
Sotheby’s launched a worldwide exhibition tour of the blue diamond, beginning with its unveiling at their inaugural show in Abu Dhabi. It was then displayed across the Middle East, Asia, and the United States, generating significant interest from collectors and high-net-worth buyers. The gem was showcased alongside seven other ultra-rare diamonds and gemstones, with the total collection valued at over $100 million.

A Defining Stone of the Season
Quig Bruning, Sotheby’s Head of Jewelry for the Americas & EMEA, described the diamond as a milestone for the season:

“It is undoubtedly the defining stone of the season and ranks among the top blue diamonds we have ever sold. The excitement it generated during its global tour reflects the increasing demand for rare, investment-grade diamonds and a growing flight to quality among collectors.”
