31-Carat ‘Desert Rose’ Diamond Expected to Fetch $7 Million at Abu Dhabi Auction

Sotheby’s is set to showcase one of the world’s rarest diamonds during its upcoming series of luxury auctions and exhibitions in Abu Dhabi, held from 2 to 5 December at The St. Regis Saadiyat Island Resort. The events form part of Abu Dhabi Collectors’ Week, which will feature masterclasses, panel discussions, and curated exhibitions highlighting fine jewellery, timepieces, collector cars, luxury real estate, and other exceptional assets.

The highlight of the auction is “The Desert Rose”, a 31.86-carat fancy vivid orangy-pink diamond, the largest of its kind ever graded. This extraordinary pear-shaped gem—first unveiled in Sotheby’s “Beyond: The World’s Rarest Diamonds” exhibition earlier this year—makes its auction debut with an estimated value of USD $5–$7 million.

The timing of the event coincides with one of Abu Dhabi’s busiest weeks, which includes the Formula 1 Grand Prix, the Milken Institute Middle East and Africa Summit 2025, Abu Dhabi Finance Week, and Bitcoin MENA. Together, these prestigious gatherings are expected to attract a global audience of collectors, investors, and cultural leaders.

Following Sotheby’s successful inaugural sale in Saudi Arabia earlier this year, the Abu Dhabi auctions further underscore the Middle East’s growing influence in the global luxury and cultural landscape. Saadiyat Island, home to institutions such as the Louvre Abu Dhabi, the forthcoming Guggenheim Abu Dhabi, and the Zayed National Museum, continues to establish itself as a world-class destination for art and high-value collectibles.

The Desert Rose diamond’s debut marks a milestone in coloured diamond history—its rarity, hue, and size exemplify the exceptional standards that define the world’s most coveted gems.

Unique Patek Philippe Sells for $4.3m

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.

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

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.

The 10.3 Carat ‘Mediterranean Blue’ Diamond Could

Sotheby’s to Auction Exceptionally Rare 10.3-Carat Fancy Vivid Blue Diamond

Fancy vivid blue diamonds exceeding 10 carats are among the rarest gemstones in the world, and Sotheby’s is set to present one at its High Jewellery sale in Geneva on 13 May.

Known as “The Mediterranean Blue,” this extraordinary 10.3-carat fancy vivid blue diamond – the highest grading for a blue diamond – has been assessed by the Gemological Institute of America (GIA) with a VS2 clarity rating. It is also classified as a Type IIb diamond, a category that accounts for less than 0.5% of all diamonds, according to the auction house.

This cushion-shaped modified brilliant diamond is expected to be a highlight of the auction, with an estimated value of around $20 million.

“Any vivid blue diamond is a significant discovery, but one as mesmerising as this, especially over 10 carats, is truly newsworthy,” said Quig Bruning, Sotheby’s Head of Jewellery, Americas & EMEA. “The Mediterranean Blue’s remarkable size, elegant cushion cut, and striking ocean-blue hue place it among the most important blue diamonds to appear on the market in recent years.”

Before the auction, The Mediterranean Blue will be unveiled on 8 April at the Bassam Freiha Art Foundation in Abu Dhabi, a remarkable dune-shaped architectural structure. This non-profit institution, founded by philanthropist and art collector HE Bassam Said Freiha, houses an extensive collection of Orientalist art. The foundation is located on Saadiyat Island, home to renowned cultural landmarks such as the Louvre Abu Dhabi and the upcoming Guggenheim Museum. This marks Sotheby’s first public exhibition in Abu Dhabi since 2009, with further details on the unveiling to be announced in the coming weeks.

A Diamond of Remarkable Origin
Sotheby’s revealed that The Mediterranean Blue was cut from a 31.94-carat rough diamond, discovered in 2023 at the Cullinan mine in South Africa. The transformation into a finished gem involved a year of meticulous study, followed by six months of precise planning and cutting.

Blue diamonds of substantial size and exceptional quality rank among the most valuable gemstones ever sold at auction. In fact, two of the three most expensive diamonds ever auctioned were blue diamonds. Most of these rare gems originate from the Cullinan mine, which has produced some of the world’s most famous diamonds, including the 530-carat Great Star of Africa, the largest faceted colourless diamond ever discovered.

Historic Blue Diamonds from the Cullinan Mine
Other legendary blue diamonds sourced from the Cullinan mine include:

The Blue Moon of Josephine – A 12.03-carat, cushion-cut, internally flawless fancy vivid blue diamond, which sold for $48.5 million (over $4 million per carat) at Sotheby’s Geneva in 2015.
The De Beers Blue – A 15.10-carat, step-cut fancy vivid blue diamond, which fetched $57.5 million at Sotheby’s Hong Kong in 2022.
The De Beers Millennium Blue – A 10.10-carat, oval-shaped, internally flawless diamond, which sold for $31.8 million at Sotheby’s Hong Kong in April 2016.
The Oppenheimer Blue – A 14.62-carat fancy vivid blue diamond that holds the world auction record for a blue diamond at $57.5 million, sold by Christie’s in Hong Kong in May 2016.
According to the GIA, only 0.3% of all diamonds submitted for grading annually exhibit a predominantly blue colour, and of these, very few are classified as fancy vivid blue weighing over 10 carats.

“The attributes of The Mediterranean Blue, weighing 10.3 carats and sitting within the most sought-after fancy colour range, make it a truly exceptional diamond,” the GIA stated in Sotheby’s announcement.

This extraordinary gem is expected to draw significant attention from collectors and investors when it goes under the hammer in Geneva this May.

New York Jewelry Auctions Top $70 Million In June, Led By Diamonds

Live jewelry auctions in New York are easily keeping pace with multi-million-dollar watch auctions, and they remain the best venue for large diamonds, gemstones and signed pieces. Sotheby’s Magnificent Jewels sale in June totaled $30,033,900, and Christie’s hit the $44.4 million mark, for a combined haul of over $70 million between the two.

A 14.51 carat sugarloaf cabochon Kashmir sapphire ring that sold for $1.8 million at Sotheby’s

Fancy colored and large flawless diamonds, along with rare specimens of emerald, sapphire and ruby continue to rank in the top 10 lots at most auctions. In the Sotheby’s top 10, the seven highest-selling pieces sold for over $1 million, and the top two lots sold for over $3 million.

The auction was led by a $3.6 million piece of jewelry, a Van Cleef & Arpels necklace. The tassel-tie style long necklace was fully set with several cuts of perfectly matched diamonds in tapered sizes. It was made in 1929, and would be difficult to make or find anywhere today. The second-highest lot was a 53-carat internally flawless diamond, another rare find, especially given than diamond mining is not the prolific activity it once was. It sold for $3,480,000.

For final proof that rarity is the driving value factor at jewelry auctions, the next lots were Kashmir sapphires, the prized velvety blue gems that haven’t been mined in a century—including a 10.31-carat Kashmir sapphire and diamond ring that sold for $1,980,000, and a 14.51-carat sugarloaf cabochon sapphire ring that sold for $1.8 million. Natural pearls, also very rare, are fetching top dollar at auction as well. Among the top 10 at the Sotheby’s sale was a natural pearl, cultured pearl and diamond necklace selling for $552,000, along with exquisite pieces from Graff and Harry Winston.

Christie’s sold the the Eden Rose, a 10.2-carat fancy intense pink diamond for $13.3 million.

Phillips, which has for several years been the leading auction house when it comes to watches, also started holding live jewelry auctions this year. It got off to a good start in June with a New York sale that totaled $2.8 million. Leading the auction was a 9.81-carat emerald and diamond ring, which doubled its estimate at $165,000. A pair of diamond ear clips sold for $165,100, and a Cartier gold and diamond necklace designed as an undulating fringe sold for $146,050. The sale also included pieces from Van Cleef & Arpels, Cartier, and Bulgari and Oscar Heyman.

Van Cleef & Arpels Diamond ‘Tie’ Necklace Fetches $3.6 Million

An important and rare Van Cleef & Arpels diamond “Tie” necklace smashed its estimate and blew past other impressive gems and jewels to become the top lot at Sotheby’s Magnificent Jewels auction, held Friday in New York.

The necklace, circa 1929, composed of graduated links set with variously cut diamonds with elongated tassels that partially rotate, sold for $3.6 million, triple its high estimate of $1.2 million, after a six-minute battle between seven bidders.

It was one of the few marquee items in the sale of 95 lots, a low number for a major New York auction. However, many of the items offered were highly collectible and wearable as shown by the overall results. For example, the sale achieved $30 million, near its $35 million high estimate, with 90% of lots sold and 62% of sold lots achieving prices above their high estimate. Sotheby’s said persons from 30 countries participated in the auction, placing more than 1,200 bids. In addition, seven out of the 10 most valuable jewels in the sale achieved more than $1 million. Art Deco jewels, Kashmir sapphires and white diamonds all performed well.

Quig Bruning, Sotheby’s Head of Jewels for Americas & EMEA, credits Sotheby’s new lower buying premium, set at 20%, for the strong overall results.

“We’re encouraged to see that two-thirds of jewels have sold above their high estimates since our lower buyer’s premium came into effect on May 20, confirming that a fairer fee structure is the definition of client-first, and not only encourages more buyers to participate at auction, but also reiterates that Sotheby’s is open to all.”
