Phillips to Offer 6.21-Carat Vivid Pink Diamond

Colored gemstones and signed jewels are the focus of its upcoming Geneva sale.

A top lot in part two of Phillips’ Geneva Jewels Auction, this 6.21-carat fancy vivid pink diamond is estimated to sell for 9.5 million to 13.6 million CHF ($10.5 million to $15 million).
Geneva—A 6.21-carat fancy vivid pink diamond is the highlight of Phillips’ upcoming Geneva auction, and it’s estimated to sell for up to 13.6 million CHF ($15 million).

The pink diamond, pictured at the top of the article, will be offered alongside more than 100 other lots in “The Geneva Jewels Auction: Two,” which will be held May 13 at Hotel President Geneva.

With a strong saturation and very vivid hue, Phillips said, the pink diamond has a “flawless polish and symmetry … and exceptional purity and transparency.”

It is also classified as a Type IIa diamond, meaning it has no measurable nitrogen or boron impurities and, according to GIA, is chemically most pure.

From the property of a private collector, a 1.56-carat fancy red diamond is also a highlight of the upcoming sale and is estimated to sell up to 1.4 million CHF ($1.5 million).

Named “The Argyle Phoenix,” the diamond was sourced from the now-closed Argyle mines in Australia.

“The Argyle Phoenix,” a red diamond, is expected to sell at Phillips next month for 910,000 to 1.4 million CHF ($1 million to 1.5 million).


Predominantly red diamonds, meaning ones with no secondary hue, are among the rarest of colored diamonds. GIA records show that, from 1957 to 1987, there was no mention of a GIA lab report issued for a diamond with “red” as the only descriptive term.

Its rarity is heightened by its brilliant cut, an uncommon cutting style for colored diamonds due to the amount of material lost, as the stones’ value leads cutters to prefer cuts that preserve weight. Another rare brilliant-cut colored diamond was the focus of Phillips’ recent Hong Kong sale.

The red diamond is accompanied by a GIA monograph, illustrating its rarity and quality.

From the same private collector, a 280.84-carat Colombian emerald named “The Amazon Queen,” is on offer.

At more than 280 carats, “The Amazon Queen” is one of the largest gem-quality emeralds to be offered at auction, Phillips said.


With minor oil, it is one of the largest gem-quality emeralds to appear at auction, Phillips said. 

Its pre-sale estimate is 1.4 million to 2.4 million CHF ($1.5 million to $2.6 million). 

Also featured from the private collection is a Harry Winston yellow diamond necklace featuring an 11.28-carat pear-shaped fancy intense yellow diamond, as well as a 2.26-carat fancy intense green diamond with VS1 clarity. 

 

Along with colored gemstones, the sale will showcase signed jewels from Cartier, JAR, Sterlé, Suzanne Belperron, Van Cleef & Arpels, and others. 

“As our jewels department experiences continued growth and expansion, we are proud to unveil these exquisite highlights in anticipation of our second jewels auction in Geneva this May. The Geneva Jewels Auction: Two promises an extraordinary array of treasures, led by the breathtaking 6.21-carat fancy vivid pink diamond ring,” said Benoît Repellin, Phillips’ worldwide head of jewelry.  

“With great excitement, we embark on our first season at the esteemed Hotel President Geneva, where we look forward to welcoming our community of clients and collectors to this wonderful new venue.”

Also, an oval diamond ring weighing 10.08 carats is estimated to fetch up to 360,000 CHF ($400,000).

Also, a pair of Kashmir sapphire and diamond ear clips weighing 2.48 and 2.68 carats are estimated to sell for up to 90,000 CHF ($100,000).

Exemplifying the classic Panther design, Phillips said the necklace “encapsulates the timeless elegance and iconic style synonymous with Cartier.” 

A pair of chalcedony, pink opal, and diamond ear clips from JAR, along with a Sterlé diamond brooch from the 1960s, will be offered as well. 

 
Wrapping up the singed jewels highlights, pieces from Suzanne Belperron and Van Cleef & Arpels “capture the pinnacle of craftsmanship and timeless allure,” the auction house said.

Additional top lots include a Suzanne Belperron chalcedony and pearl brooch, circa 1955, estimated to sell for up to 60,000 CHF ($65,000), as well as gold and diamond clip brooches, circa 1940, from Van Cleef & Arpels with a high-end estimate of 28,000 CHF ($30,000). 


Complementing the live auction, Phillips will present “Symbols, Colour and Form,” an additional jewels sale with offerings from Alix Dumas and Dyne.

“We are delighted to showcase Symbols, Colour and Form, a spring selling exhibition featuring contemporary jewels from Maison Alix Dumas and Dyne, highlighting the epitome of high-quality craftsmanship in modern design,” Repellin said.

Alix Dumas' sculptural designs exude movement and sensuality, Phillips said, drawing inspiration from diverse sources to infuse touch and texture into each piece. 

Included in the selling exhibition is Dumas’ “Fleur de Magnolia” diamond, spinel, and sapphire brooch, a piece that led to a win for its designer in the Couture Design Awards’ “Best in Haute Couture” category in 2023.

No estimates were available for any piece highlighted for the Symbols, Colour, and Form exhibition at the time this article was published.

Another highlight of the exhibition is Dumas’ spinel, tsavorite, and sapphire “Eclosion” ring.

From Dyne, Phillips will offer a peach gold and diamond “Cinnamon” ring and texturized band, a gold and emerald “Nemes” ear cuff, and a “Candy” ring.

Standout jewels from Symbols, Colour, and Form will go on an international preview tour alongside highlights from the Geneva Jewels Auction: Two before returning to Geneva for viewings May 8-13 and the exhibition, also at Hotel President. 

The lots were in New York earlier this month and will go on to be displayed in London from April 12-14, Taipei, Taiwan from April 20-21, and lastly, Singapore from April 26-28.

More information about the auction is available on Phillips website.
