6.03 Carat Internally Flawless Blue Diamond Unsold at Major Geneva Auction

 

A rare 6.03 carat fancy vivid blue internally flawless diamond failed to secure a buyer at the recent Sotheby’s Geneva High Jewelry Sale, despite carrying a pre sale estimate between USD $9 million and $12 million. The exceptional blue diamond was the headline lot of the May 12 auction held at the Mandarin Oriental in Geneva.

Although the blue diamond remained unsold, the auction itself was considered a strong success, achieving more than USD $30 million in total sales with 93% of lots sold. Sotheby’s reported its highest participation levels in a Geneva jewellery sale in more than five years, with an average of more than five bidders competing for each sold lot.

Collectors from over 30 countries participated in the auction, with strong interest from buyers across the United States, Asia, Europe and the United Kingdom. Fancy coloured diamonds, important gemstones and signed vintage jewellery continued to dominate buyer demand.

According to Jessica Wyndham, Head of High Jewelry at Sotheby’s Geneva, collector appetite for coloured gemstones remains exceptionally strong, while white diamonds are also experiencing renewed demand. Signed jewellery from iconic maisons, particularly bold 1970s and 1980s designs from Bulgari, significantly exceeded expectations during the sale.

The top performing lot of the auction was a perfectly matched pair of unmounted diamonds, each weighing 18.38 carats. Both diamonds were graded Type IIa and D colour, with one graded flawless and the other internally flawless. The pair sold for more than USD $3.2 million. The diamonds were sourced by De Beers from Botswana’s renowned Jwaneng Mine as part of a collaboration with Sotheby’s showcasing exceptional provenance diamonds.

Another standout lot was the “Peacock of Ceylon,” a remarkable 102.4 carat unheated cushion cut sapphire, which achieved nearly USD $2 million at auction.

A further highlight included a 4.12 carat pear shaped fancy pink internally flawless diamond ring, which sold for USD $1.4 million. The Type IIa diamond, graded by the Gemological Institute of America, featured excellent polish and was mounted between tapered baguette diamond shoulders.

The failure of the vivid blue diamond to sell highlights the increasingly selective nature of today’s high end gemstone market, where rarity alone is no longer enough to guarantee a record result.

World Diamond Day: The Most Valuable Diamonds Ever Sold at Auction

In recognition of World Diamond Day, we reflect on some of the most extraordinary diamonds ever offered at auction stones that not only achieved record-breaking prices but also represent the pinnacle of rarity, craftsmanship, and natural beauty.

Established by the Natural Diamond Council, World Diamond Day celebrates the enduring significance of natural diamonds, highlighting their provenance, emotional value, and the moments they commemorate. It is also an opportunity to examine the exceptional stones that continue to define the upper limits of the global diamond market.

Below is a selection of some of the most important diamonds ever sold at auction.

---

The CTF Pink Star

The CTF Pink Star remains the most expensive diamond ever sold at auction. This 59.60 carat oval-shaped, fancy vivid pink diamond achieved US$71.2 million at Sotheby’s Hong Kong in 2017.

Internally flawless and cut from a 132.5 carat rough discovered in 1999, the stone required over two years of meticulous planning and craftsmanship to realise its final form. It was acquired by Chow Tai Fook, setting a benchmark for coloured diamonds globally.

---

The Williamson Pink Star

Achieving US$57.7 million in 2022, this 11.15 carat cushion-cut fancy vivid pink diamond is among the finest ever graded.

Originating from a 32.32 carat rough from Tanzania’s Williamson mine, it was classified as internally flawless by the Gemological Institute of America, placing it among the rarest gemstones known.

---

The Oppenheimer Blue

This 14.62 carat emerald-cut vivid blue diamond sold for US$57.5 million at Christie’s Geneva in 2016.

Named after its former owner, Sir Philip Oppenheimer, the diamond drew intense global attention and was ultimately secured after a competitive international bidding process.

---

The Blue Moon of Josephine

Cut from a 29.62 carat rough discovered in South Africa in 2014, this 12.03 carat fancy vivid blue diamond achieved US$48.4 million at Sotheby’s Hong Kong in 2015.

Purchased by Hong Kong collector Joseph Lau, it was renamed in honour of his daughter, further cementing its place in modern diamond history.

---

The Graff Pink

This 24.78 carat fancy intense pink diamond sold for over US$46 million at Sotheby’s Geneva in 2010.

Acquired by Laurence Graff, the stone had not appeared on the market for more than 60 years prior to its sale, adding to its provenance and desirability.

---

The Princie Diamond

Selling for US$39.3 million at Christie’s New York in 2013, the Princie Diamond carries remarkable historical significance.

Originating from India’s famed Golconda mines and once owned by the Nizams of Hyderabad, the diamond reflects the rich heritage of some of the world’s most celebrated diamond sources.

---

The The Orange

Weighing 14.82 carats, this pear-shaped fancy vivid orange diamond remains the largest of its kind ever recorded.

It achieved US$35.5 million at Christie’s Geneva in 2013, significantly exceeding pre-sale expectations and reinforcing the rarity of orange diamonds.

---

The Magnificent Oval Diamond

One of the largest D-colour flawless diamonds ever to appear at auction, this 118.28 carat oval-cut stone sold for US$30.8 million at Sotheby’s Hong Kong in 2013.

Its exceptional colour and clarity grading underscore the importance of strict laboratory standards in determining value—an area where independent certification remains critical.

---

A Reflection on Rarity and Value

These diamonds are more than record-breaking assets—they are geological miracles shaped over billions of years and refined through exceptional human skill. Their value lies not only in carat weight or colour grading, but in rarity, provenance, and the precision of their cutting and certification.

As World Diamond Day highlights, natural diamonds continue to occupy a unique position in both the luxury and investment landscape. For laboratories such as the Diamond Certification Laboratory of Australia, the role of accurate and independent grading remains fundamental in preserving confidence and transparency within the global diamond market.

3.63-ct “Salt and Pepper” Pink Fails to Sell

The highlight of Sotheby’s Fine Jewelry sale in New York – a rare 3.63-carat fancy vivid purple-pink diamond failed to find a buyer.

The unmounted, cut-cornered rectangular modified brilliant-cut stone carried a pre-auction estimate of $1m to $1.5m , reflecting both its unusual color and its potential appeal to collectors.

But bidding at the auction, on 11 December, stalled below the consignor’s undisclosed reserve, leaving the stone unsold.

Market observers suggested that bidders were likely deterred by the diamond’s noticeable “salt and pepper” inclusions, which significantly affected its clarity.

The Gemological Institute of America (GIA) graded the stone as I2 clarity, raising concerns about transparency and overall visual appeal.

Observers say buyers in today’s cautious high-end market are increasingly unwilling to compromise on clarity, particularly for unmounted stones, where inclusions are more apparent, even when the color is considered rare and desirable.

$20 Million ‘Glowing Rose’ Pink Diamond to Headline Sotheby’s Geneva Auction

A rare 10.08-carat fancy vivid pink diamond ring, named The Glowing Rose, is set to take centre stage at Sotheby’s upcoming High Jewellery sale in Geneva on 12 November. Expected to achieve around USD 20 million, the stone represents one of the most important pink diamonds to reach the auction block in recent years.

This exceptional cushion brilliant-cut diamond crafted by luxury jeweller Boodles originates from a 21-carat rough unearthed in Angola in 2023. Its vivid, pure pink hue and balanced proportions exemplify the rarest qualities of natural fancy coloured diamonds. According to Sotheby’s, it is only the third cushion cut vivid pink diamond over 10 carats to appear at auction within the past decade.

The cushion cut, recently popularised by Taylor Swift’s engagement ring, has become increasingly sought after among collectors for its romantic and timeless appeal.

Sotheby’s has a strong record of achieving exceptional results for vivid pink diamonds. In 2022, the auction house sold the Williamson Pink Star an 11.15 carat, fancy vivid pink, internally flawless diamond for USD 57.7 million in Hong Kong. The following year, a 10.57 carat vivid purplish-pink diamond fetched USD 34.8 million in New York. Earlier this year, Sotheby’s Geneva achieved USD 21.5 million for the Mediterranean Blue, a 10.03-carat fancy vivid blue diamond.

“With the continued global demand for rare coloured diamonds, we are delighted to present The Glowing Rose,” said Jessica Wyndham, Head of High Jewellery at Sotheby’s Geneva. “Following the remarkable success of the Mediterranean Blue, this sale offers collectors another extraordinary opportunity to acquire a truly exceptional gem.”

Before its appearance in Geneva, The Glowing Rose will be showcased in Singapore and Taipei, giving collectors and connoisseurs a preview of one of the year’s most significant pink diamonds.

DCLA notes that fancy vivid pink diamonds remain among the most coveted and valuable gems in the world, combining extraordinary rarity with strong global demand from collectors and investors alike.

Lucara Recovers Rare 37-Carat Pink Diamond from Karowe

Lucara Diamond Corp. has announced the recovery of a rare and unusual pink diamond from its Karowe mine in Botswana.

The 37.42-carat stone, classified as a Type IIa, was unearthed in August and is described as near-gem quality with a distinctive bicoloured appearance. While the majority of the diamond displays an intense pink hue, part of the stone appears partially colourless an exceptionally rare feature.

HB Antwerp, Lucara’s cutting and technology partner, described the discovery as “a rare and remarkable find.” Oded Mansori, co-founder of HB Antwerp, noted:
“This stone has the potential to become one of the most important pink diamonds ever polished. Its intensely rich coloration is a testament to the geological uniqueness of the Karowe mine, and our expertise in the manufacturing process will ensure its vibrant colour is maximised.”

The recovery underscores Karowe’s reputation as a consistent source of exceptional diamonds. Also in August, Lucara recovered a 1,019.85-carat non-gem-quality diamond, the third stone of more than 1,000 carats to be found at Karowe in 2025. This brings the total number of diamonds over 1,000 carats from the mine to nine.

Both diamonds were recovered from the EM/PK(S) section of the deposit using Lucara’s Mega Diamond Recovery (MDR) unit, an advanced X-ray transmission system installed in 2017 to identify and preserve large stones. The MDR is credited with detecting several of Karowe’s most significant recoveries, including the 2,492-carat diamond discovered in August 2024—the second-largest rough diamond ever found.

Meanwhile, Lucara has announced a $10 million drawdown from its $63 million standby loan facility with Nemesia, its largest shareholder, to address short-term funding needs for the Karowe underground expansion project. The $683 million project, now scheduled for completion in the first half of 2028, is expected to extend the mine’s life to at least 2040.

Lucara President and CEO William Lamb said the arrangement reflects the company’s commitment to financial prudence while advancing the underground project.
“This funding mechanism demonstrates the continued confidence and support of our major shareholders in Lucara’s long-term strategy and in the exceptional value potential of the Karowe mine, including the ongoing recovery of some of the world’s most significant diamonds.”

See The World’s Rarest Diamonds, Worth a Total of $100 million, in Abu Dhabi

Sotheby’s, in partnership with the Abu Dhabi Investment Office, is exhibiting extremely rare coloured diamonds at Bassam Freiha Art Foundation this week, in the biggest showcase of diamonds outside of the Smithsonian Museum in Washington DC.

All together, the spectacular diamonds are worth around $100 million. The largest flawless diamond in the world, the largest vivid orangey pink diamond ever graded, the second largest red diamond known to exist and several diamonds over 100 carats are included in the collection, which will be available for public view this Wednesday, April 9 and Thursday, April 10.

“The exhibition is incredibly exciting for the simple reason that to purely just have eight diamonds of this calibre in the same room is something that is worthy of one of the great museums in the world, and I can’t imagine that we will ever see this array together again,” says Paul Redmayne, Sotheby’s senior vice president for luxury private sales. “It is definitely a career highlight for me to see these stunning gemstones side by side, and I look forward to no doubt witnessing many a jaw drop as the public come through the doors.”

The star of the showcase is none other than The Mediterranean Blue. Weighing 10.03 carats, this Fancy Vivid Blue rarity has earned the highest GIA colour grading and a coveted Type IIb classification, an elite status held by less than 0.5 per cent of diamonds. Its cushion cut intensifies its liquid-like saturation, an electrifying depth that feels almost surreal. With an estimated value of $20 million, The Mediterranean Blue will be the highlight of Sotheby’s High Jewellery Sale on May 13 in Geneva.

“The Mediterranean Blue diamond on its own is an incredibly rare stone, and ticks so many of the boxes that you could look for: it is a connoisseur’s diamond, whilst also being infinitely wearable,” shares Redmayne. “The depth of the blue is unrivalled, and even to someone who knows nothing about diamonds, it’s clear to see what makes it so special.”

The diamond is a timeless symbol of love, power, beauty and status – but a captivating collection of this stature is awe-inspiring at an entirely different level; a once-in-a-lifetime experience in the UAE’s capital city, which Redmayne says marks an incredibly exciting moment in the city’s history. “This project further enriches the dynamic landscape of Abu Dhabi for both collectors and the general public,” he says.

Petra’s entire interest in Williamson headed for Tanzania’s Pink Diamonds

An agreement has been entered into for the outright sale of Williamson Diamonds Limited, Petra Diamonds announced on Wednesday.

The London-listed and South Africa-active Petra is taking steps to sell its entire shareholding in the Tanzanian entity to Pink Diamonds Investments for a headline consideration of up to $16-million.

This follows Petra’s sale in May of just under half of the asset, in which the Tanzanian government has a stake, for $15-million via long-term technical services contractor Taifa Mining.

Since then, Williamson’s coming under consolidated ownership has emerged increasingly as the preferred way forward.

As a Taifa affiliate, Pink Diamonds is viewed by Petra CEO Richard Duffy as possessing the technical and financial capability to conduct operations in a responsible manner for all stakeholders.

As a wholly Tanzanian-owned company with more than three decades of mining-related experience, Taifa’s working relationships extend to mining majors such as De Beers, Barrick and AngloGold Ashanti. It is now entering a phase of exclusive ownership of the asset where about 1 100 people are employed, most of them Tanzanian.

The mine’s reserves and resources as of June 30 were reported as 37.17-million carats. With liquidity challenges continuing, further capital investment will be required.

“We look forward to working closely with the Mining Commission, the Fair Competition Commission, employees, community representatives and other key stakeholders in completing the sale as soon as possible,” Duffy stated in a stock exchange announcement accessed by Mining Weekly.

In South Africa, Petra operates the Cullinan diamond mine in Gauteng and the Finsch diamond mine in the Northern Cape.

“We’re committed to adopting and adhering to the latest internationally recognised standards throughout all aspects of our business,” said Pink Diamonds chairperson Rostam Azizi, whose family are from the area around Mwadui, the other name for the Williamson mine, which is situated 23 km north-east of Shinyanga in northern Tanzania.

Mining Weekly can report that the discovery of the kimberlite pipe by Canadian geologist John Williamson in 1940 led to ongoing operation since then, making it one of the world’s oldest continuous operating diamond mines. Its yield of 19-million-plus diamond carats includes the 54.5 ct Williamson pink diamond presented to British royalty in 1947.

10.20-Carat ‘Eden Rose’ Diamond Could Fetch $12 Million At Christie’s

Christie’s will offer “The Eden Rose,” a 10.20-carat round brilliant fancy intense pink diamond, as the top lot of its New York Magnificent Jewels auction on June 11. Its estimate is $9 million to $12 million. It is the first time this diamond has appeared at auction.

The Gemological Institute of America report supplied by Christie’s states that the diamond is also internally flawless.

Describing it as an “exceptionally rare gemstone,” Christie’s says the gem, named after the symbol for unconditional love, it is the most significant round brilliant internally flawless fancy intense pink diamond to be offered at auction since the “Martian Pink,” which sold at Christie’s Hong Kong in 2012 for $17.4 million, equating to $1.45 million per carat.

The diamond exhibits a pure pink hue, unlike many natural pink diamonds that typically display secondary hues such as purple, orange or gray. “The Eden Rose stands out for its complete absence of any secondary color, rendering it exceptionally rare,” Christie’s said in a statement.

Rahul Kadakia, Christie’s International head of Jewelry, said in a statement that he is “anticipating significant interest from around the world.”

Christie’s says the round brilliant cut is known for its ability to maximize light reflection and is considered the ideal cut for diamonds.

The Eden Rose is mounted on a ring further adorned with eight brilliant-cut diamonds, ranging in weight from 3.11 to 0.73 carats, and two marquise brilliant-cut diamonds of 2.24 and 1.02 carats.

 Rio Tinto unveils Argyle Rose heirloom piece

Rio Tinto has unveiled the latest heirloom piece of Argyle Pink Diamonds jewellery, featuring one of the last diamonds to be mined from the iconic Argyle mine in the East Kimberley, Western Australia.

Mining ended at Argyle in November 2020, after 37 years of uninterrupted production, during which the mine became the source of about 90% of the world’s prized rose-to-magenta hued stones. The mine produced more than 865 million carats of rough diamonds.

Designed by Western Australian jeweller Solid Gold Diamonds, the Argyle Rose features a total of 3.25 carats of rare Argyle pink and blue diamonds encrusted in a rose motif, surrounded by white diamonds and hand-set in platinum and 18 karat gold.

The heart of this piece is an extremely rare 1.36 carat, Fancy Deep Pink radiant cut diamond. It is just one of twelve radiant cut diamonds over one carat with a colour grading, 1P, from the last 30 years of production from Argyle.

The surrounding petaled design of pink and blue Argyle Diamonds totals 1.89 carats, together with 2.80 carats of white diamonds. The Argyle Rose is for sale at Solid Gold Diamonds in Perth for A$2 million.

“I am delighted to launch the Argyle Rose. Encapsulating a rich history and an extraordinary provenance, it is both a contemporary treasure and an heirloom for tomorrow,” Sinead Kaufman, Chief Executive of Rio Tinto Minerals said in a statement.

“These rare and precious diamonds are one and a half billion years old, from one of the most beautiful places on earth, and the world is simply not producing them anymore.”

Storm Mountain Diamonds finds giant pink rock in Lesotho

Storm Mountain Diamonds (SMD), jointly owned by Namakwa Diamonds Limited and the Government of Lesotho, has recovered a 108.39-carat fancy pink diamond at its Kao Mine in the Southern African country.

The diamond is one of the largest pink roughs ever found in Africa, which include the “Lulo Rose”, 170-carat precious stone recovered by Australia’s Lucapa Diamond in Angola last year.

SMD said the diamond was recovered from a 1.5 tonne sample of kimberlite ore that was processed at the mine’s plant.

It is a Type IIa stone, which means it has very few impurities and a high level of clarity, the company said.

The Kao Mine is one of the largest diamond mines in Lesotho and produces about 400,000 carats of diamonds annually.

Coloured diamonds, especially pink ones, have repeatedly set record-setting prices in recent years as they are rarer than white ones. While they come in many hues, pink and blue are the most coveted.

Pink and yellow diamonds from two iconic Rio Tinto mines – Argyle and Diavik – have been brought together to create a unique ring.

It’s called Diavik Midnight Sun and has been valued at $1.24m.
