Rare Half-Pink 37.4-Carat Diamond Unearthed in Botswana

A remarkable two-coloured natural diamond has been discovered in Botswana, astonishing experts with its size and formation. The gem half pink and half colourless weighs an impressive 37.41 carats and measures approximately 24.3 x 16 x 14.5 millimetres, according to the Gemological Institute of America (GIA).

The GIA describes the stone as having formed in two distinct geological stages. Sally Eaton-Magaña, Senior Manager of Diamond Identification at the GIA, explained that the pink section likely began as colourless before undergoing plastic deformation possibly caused by a mountain-forming event millions of years ago. This natural deformation altered the crystal lattice, giving rise to the diamond’s vivid pink hue. The colourless section, in contrast, appears to have formed later under more stable conditions.

Pink diamonds are among the rarest gems on Earth, prized for their beauty and scientific intrigue. Unlike coloured diamonds that owe their hue to trace elements or radiation exposure, pink diamonds result from structural distortions within the crystal lattice. This phenomenon must occur under highly specific pressure and temperature conditions too little deformation and the diamond remains colourless; too much and it turns brown.

“It’s a geological balancing act like Goldilocks,” noted Curtin University geologist Luc Doucet, referencing the fine threshold that determines a diamond’s colour outcome.

What makes this new discovery even more extraordinary is its size. While other bi-coloured diamonds have been documented, they are typically no larger than 2 carats. The 37.4-carat specimen from Botswana represents a significant leap in both scale and scientific importance.

The diamond was unearthed at Lucara Diamond Corporation’s Karowe mine, one of the world’s most productive sources of exceptional diamonds. The Karowe mine has previously yielded some of the most celebrated finds in modern history, including the 2,488-carat “Motswedi” diamond, the second-largest rough diamond ever recovered, and the 62-carat “Boitumelo” pink diamond.

This latest discovery further cements Botswana’s position at the forefront of the global diamond industry and provides scientists with another remarkable glimpse into the complex natural processes that create the Earth’s most coveted gemstones.

$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.”

The Kao Legend Collection: A Rare Suite of Pink Diamonds from Lesotho

The Kao Legend Collection represents an extraordinary achievement in diamond cutting and curation. Cut from a single 108.39-carat pink diamond crystal unearthed at the renowned Kao Mine in Lesotho, this suite features seven magnificent pink diamonds each documented in detail by the GIA Monograph.

At the heart of the collection lies the Kao Legend, a 20.49-carat diamond graded Fancy Intense Purplish Pink by the Gemological Institute of America (GIA). The accompanying diamonds in the collection range in colour from Fancy Intense Purplish Pink to Faint Pink, showcasing a delicate and rare spectrum of pink hues.

What sets this collection apart is not only its shared origin and harmonious beauty but also the diamonds’ classification. All seven are Type IIa diamonds known for their exceptional chemical purity and rarity, comprising less than 2% of all natural diamonds. Type IIa pink diamonds are especially coveted for their remarkable clarity and vibrant colour saturation.

The Kao Mine, one of Lesotho’s most prominent diamond sources, has established a reputation for yielding high-quality pink diamonds. Alongside the Kao Legend, the mine also produced the celebrated Pink Eternity, a 47.80-carat gem of international acclaim.

For gemmologists and collectors alike, the Kao Legend Collection exemplifies nature’s artistry and the pinnacle of diamond excellence.

Rare purple diamond unearthed at Diavik

Vibrant 0.45-carat gem adds final flourish to Diavik’s closing years.
Just when it seemed Diavik had given all it could give, a rare purple diamond has been unearthed at the Northern Canadian mine – a 0.45-carat stone that stands out in a region better known for producing predominantly colorless gems and the occasional yellow stone, adding a splash of unexpected color as the operation approaches the final years of its mine life.

The discovery, quietly announced by Rio Tinto via social media, comes just weeks after the recovery of a 158.2-carat yellow diamond and a 50-million-year-old petrified log – both of which drew attention to the remarkable geological and historical treasures still surfacing from the remote subarctic site.

“We recently had a unique discovery at Diavik – a rare purple diamond weighing in at 0.45 carats,” the company wrote in a social media post on LinkedIn.

“Diavik diamonds are typically white, so this came as a pleasant surprise,” the post continued. “The purple colour likely comes from a trace element such as hydrogen or a twist in the crystal lattice structure of the diamond. The shape of the rough diamond is known as a ‘makeable’ which means it will likely be cut into a single diamond.”

Though small in size, the stone is striking for its rarity, with colored diamonds of any kind making up less than 1% of Diavik’s total production over more than two decades of operation.

Among them, purple diamonds are the rarest, their distinctive hue typically attributed to hydrogen impurities or plastic deformation deep in the Earth’s mantle – a result of the intense pressure and heat that alters the crystal structure during formation.

In gemological terms, purple diamonds are often classified under the broader category of “fancy color” stones, though few attain the deep saturation necessary for that label. More often, their shades fall within the purplish-pink or violet spectrum, with pure purple standing as one of the most elusive colors in the diamond world.

For Diavik, the recovery of such a specimen near the end of its mine life serves as both a scientific curiosity and a symbolic capstone.

Since beginning production in 2003, the mine has yielded over 140 million carats of rough diamonds – predominantly colorless, with a handful of exceptional yellow stones including the 552-carat “egg” discovered in 2018 and the more recent 158.2-carat find earlier this year.

Yet, while the occasional yellow diamond has offered moments of brilliance, the purple discovery stands out for its singularity.

While not the first purple diamond recovered from Diavik – industry veterans have noted smaller specimens dating back more than a decade – this 0.45-carat stone ranks among the most notable, particularly for its size, clarity, and timing near the end of the mine’s operational life.

Purple diamonds are so rare that only a few notable examples have surfaced globally, often fetching premium prices far beyond their white or even pink counterparts. Their appearance in the trade is sporadic, and their origin even more geographically restricted – making a Canadian purple diamond an especially uncommon occurrence.

Diavik’s purple gem is expected to be cut into a single polished stone, though no details have been released about where it might end up – in private hands, a high-profile auction, or perhaps a Canadian institution.

Whatever its path, the find adds a final chapter to Diavik’s legacy – a small but vibrant reminder that even in its twilight, the remote Arctic mine remains full of surprises.

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.

Red and Pink Diamonds Lead Sotheby’s Sale

A 16.73 carat very light pink diamond is expected to sell for CHF 1.1m to CHF 1.8m ($1.3m to $2m) in Sotheby’s Geneva Magnificent Jewels Sale.

They’ll be offered for sale next week (13 November) in a live auction of 88 lots, including pieces by Cartier, Van Cleef & Arpels, Tiffany, Bulgari and JAR, spanning 250 years of jewelry history.

The pink diamond is claw-set in a ring, VVS1-clarity, natural color with a brilliant cut. The red diamond is also claw-set in a ring, with a cut-cornered rectangular mixed cut, together with an Argyle mine presentation case.

“The sale is a celebration of exceptional craftsmanship, with signed jewels from the most esteemed makers of the 20th century,” says Sotheby’s. The sale also offers a number of coloured diamonds of outstanding quality and size, within the rarest of colors.”

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.

Junior miner recovers spectacular pink diamond from banks of Middle Orange River

JOHANNESBURG- A junior diamond mining company has recovered a spectacular pink diamond from the banks of the Middle Orange River.

The diamond, named Protea Pink, is a fancy pink, 29.52 ct type II diamond, with unusual depth of colour and exceptional clarity. Its colour is reminiscent of the pink hues found in South Africa’s national flower, the protea.

This diamond was most likely derived from the 90-million-year-old Lesotho kimberlites and made a remarkable journey down the Orange river to be trapped in an ancient river terrace, approximately 500 km from its source, South African Diamond Producers Organisation (Sadpo) vice-chairperson and geologist Lyndon de Meillon stated in a release to Mining Weekly.

Sadpo, an organisation that aims to streamline the diamond diggers industry, is headed by CEO Yamkela Makupula, who is a director of Pioneer Tender House, where Protea Pink will be sold on tender in South Africa during the week of 26/30 June. The sale will end on Friday 30 June.

The Middle Orange River, which is known as the area with the highest average value per carat in the world, also has the lowest grade in carat per hundred tonnes of any area actively mined, De Meillon explained.

The modern-day alluvial diamond miner utilises no chemicals in the recovery process and rehabilitation of the mining areas has been proven to improve the carrying capacity of the land, De Meillon added.

Unemployment rates in the area are alarmingly high, exceeding 70%, with mining operations, such as this one by a junior miner, playing a crucial role in supporting the local economy by providing job opportunities and stimulating economic growth.

The revenue generated from diamond mining can contribute to infrastructure development, education, healthcare, and other essential services in the community.

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.

Its per-carat estimate of more than $3.3 million is the largest such estimate ever placed on a diamond or gemstone, according to Sotheby’s.

Quig Bruning, head of Sotheby’s Jewelry, Americas, says it’s the most vivid pink diamond to ever to come to market. “This color is the most beautiful and concentrated shade of pink in diamonds that I have ever seen.”

The cushion-shaped diamond will first be on view in Hong Kong April 1 – 7 to coincide with the 50th anniversary of Sotheby’s presence in Asia. The gem will then travel to Dubai, Singapore, Shanghai, Taiwan and Geneva before being offered as the top lot at Sotheby’s New York Magnificent Jewels auction on June 8.

The 23.78-carat rough which yielded The Eternal Pink was mined by De Beers at the Damtshaa mine in Botswana. Diamond manufacturer, Diacore, took six months to cut and polish the gem into its current color, described as “bubblegum” by the auction house.

“This stunning diamond is the best of the best when it comes to exceptional pink diamonds and it is difficult to overstate its rarity and beauty,” said Wenhao Yu, chairman of Jewellery and Watches at Sotheby’s Asia.

Sotheby’s has had some experience with important pink diamonds. The auction house sold the record-breaking CTF Pink Star, a 59.60-carat oval mixed-cut Fancy Vivid Pink Internally Flawless diamond, sold for $71.2 million—a world auction record for a diamond and any gemstone or jewel—in Hong Kong in April 2017. More recently, Sotheby’s sold the Williamson Pink Star, an 11.15-carat fancy vivid pink internally flawless diamond, for $57.7 million in a single-lot auction at Sotheby’s Hong Kong on October 8, 2022, setting the world record price per carat for any diamond or gemstone at more than $5.1 million.

Colored diamonds continue to demand high prices at auction with exceptional pink and blue diamonds leading the way. It is because of their rarity, according to Sotheby’s. Of all the diamonds submitted to the Gemological Institute of America, fewer than 3% are classified as colored diamonds. Within these colored diamonds, pink is one of the rarest to occur naturally in diamonds. A diamond that is more than 10 carats, with strong color, internally flawless clarity, and classified as a “vivid pink,” the highest grade for a pink diamond is extremely rare.
