It’s hard to believe that COVID first hit just over three years ago.
After the original shock that the pandemic caused, especially when lockdowns were put in place in large parts of the world in early 2020, markets, rather than continuing to crash, instead surged higher.
Stimulus programs from both central banks and central governments, which were enormous in scope, were the primary cause of this surge, with the vast quantity of dollars fed into the system leading to one of the biggest rallies in the share market, cryptocurrencies, and even real estate on record.
Since late 2021 it’s been tough going though, with the last twelve or so months particularly challenging for most investors.
The second largest internally flawless fancy vivid pink diamond to ever appear at auction was unveiled Wednesday in London by Sotheby’s. The 11.15-carat Williamson Pink Star will be sold in a single-lot auction in Hong Kong on October 5. Its estimate is $21 million.
The auction house says it has the potential to set a new per carat price record for a fancy vivid pink diamond.
“We do have the confidence that it will find a great collector and have the interest of multiple parties,” Wenhao Yu, chairman of Jewellery and Watches at Sotheby’s Asia, told Forbes on Tuesday. “It has the potential to reach a very strong price.”
He adds, “This diamond truly checks all the boxes. It has the best qualities you can have in a pink diamond.”
The current price per carat auction record for a fancy vivid pink diamond is $2,656,909 for the 18.96-carat Winston Pink Legacy, sold in 2018 by Christie’s Geneva. The largest internally flawless, fancy vivid pink diamond offered at auction is the 59.60-carat CTF Pink Star. It was sold by Sotheby’s Hong Kong in 2017 for $71.2 million, a world record for any gem or jewel sold at auction.
Yu compares the Williamson Pink Star to an exceptional work of art.
“We timed this lot to be offered between Sotheby’s modern and contemporary art auctions. That’s because instead of offering just another important diamond, we view this diamond as a work of art from mother earth and a wonder of nature,” Yu says. “It’s comparable to a Monet or a Picasso and is even more rare.”
The Williamson Pink Star is the second largest internally flawless fancy vivid pink diamond
The Williamson mine is one of the oldest operating diamond mines in the world, famous for producing what is described as “bubblegum” pink diamonds, according to the auction house. One of the best-known diamonds from the mine is the 23.6-carat Williamson Pink Diamond fashioned into a brooch by Cartier and owned by Queen Elizabeth II.
“We wanted to relate the important provenance of the Williamson mine when naming the diamond,” Yu says. “The unique saturated pink color is one of the important qualities of diamonds from this mine. It is an honor for us that after so many decades another important pink diamond comes from the Williamson mine and we can offer it at auction.”
The cushion-shaped diamond was crafted from a 32.32-carat rough diamond by Diacore, a diamond manufacturer that specializes in crafting rare, exceptional fancy-colored diamonds. The company purchased the gem in late 2021 for $13.8 million. Yu says crafting the diamond is just as important as discovering it, and Diacore is one of the few companies in the world capable of cutting and polishing such an important gem.

“Not every rough can yield a diamond of this high quality so we should also give credit to Diacore,” he says. “They really made cutting and polishing into an art. They are very skilled and experienced with the best technology and a lot of courage. It’s rare to have a vivid pink color. It’s rarer when it’s over 10 carats and even more rare if it’s internally flawless. It’s luck to find this kind of diamond that was formed underground for millions of years, and it takes a great amount of art and creativity to fashion it into a gorgeous stone with so many exceptional qualities.”
Pink diamonds are among the rarest colors to occur naturally in diamonds. Of all the diamonds submitted to the Gemological Institute of America (which analyzes and grades diamonds), fewer than 3% are classified as colored diamonds, and fewer than 5% of those are considered predominantly pink.
The Argyle Mine in Australia, before it was retired in 2020 after exhausting its supply of gem-quality diamonds, produced more than 90% of the world’s pink diamonds. The absence of pink diamonds from this mine makes important pink diamonds like the one being offered even more rare, Yu says.
“Pink diamonds are still growing in demand in the market, and this now makes the Williamson Pink Star even more sought after,” he says.
The diamond is being presented in an 18k gold ring flanked by trapeze-cut diamonds and embellished with brilliant-cut diamonds.
London is the first stop where the diamond will be viewed by the public. It will then travel to Dubai, Singapore and Taipei before the final viewing and sale in Hong Kong.
Lucapa Diamond Company has recovered one of the largest pink diamonds in history: a 170-carat stone from the Lulo mine in Angola.
The type IIa rough, named the Lulo Rose, is “believed to be the largest pink diamond recovered in the last 300 years,” Lucapa said Wednesday. It is also the fifth-largest diamond from Lulo, and the deposit’s 27th over 100 carats since commercial production began in 2015. Lucapa plans to sell the diamond through an international tender conducted by Angolan state diamond-marketing company Sodiam, it noted.
“The record-breaking Lulo diamond field has again delivered a precious and large gemstone, this time an extremely rare and beautiful pink diamond,” said José Manuel Ganga Júnior, chairman of the board of state-owned Endiama, one of Lucapa’s partners in the deposit. “It is a significant day for the Angolan diamond industry.”
In addition to the pink, Lulo is also the source of Angola’s largest diamond, a 404-carat rough named the 4th February Stone.
Lucapa has begun bulk sampling at “priority kimberlites” as it searches for the primary source of Lulo’s diamonds, managing director Stephen Wetherall added.
Diamonds from Rio Tinto’s Argyle Pink Diamond Tender.
Rio Tinto has debuted a new strategy that will enable it to “protect the provenance” of its Argyle pink diamonds, including a certification service and a concierge trading platform.
“This is the start of a new chapter for Argyle pink diamonds, to ensure they maintain their value and investment potential as a finite, unrepeatable natural resource and achieve the status of outstanding heritage diamonds,” Rio Tinto Minerals CEO Sinead Kaufman said last week.
The venture will also play host to a new Beyond Rare tender platform for special sales events, as well as several strategic collections and collaborations involving existing inventory and the secondary market.
One such venture, the Icon Partner program, will give jewelers licensing rights to use the Argyle Pink Diamonds brand for jewelry they create with any remaining inventory they previously purchased from the Argyle mine. The first two retailers Rio Tinto has authorized are John Calleija, the owner of Australian luxury-jewelry house Calleija, and Singapore-based Glajz THG, owned by John Glajz.
“The secondary market for Argyle pink diamonds comprises almost 40 years of rare, polished pink diamonds, together with heirloom pieces of jewelry, collectibles and objects,” the miner noted. “This market requires careful management to preserve the precious provenance of Argyle pink diamonds and continue the legacy of careful custody that underscores its rarity.
Petra is to offer a 32.32-carat pink diamond at its first tender of goods from the Williamson mine, in Tanzania following a Covid-enforced closure.
The stone is among 26,000 carats that will be offered in Antwerp from 19 to 26 November. The London-based miner classified Williamson as “an asset held for sale for financial reporting purposes” after a a debt-for-equity restructuring. The open-pit mine was mothballed in April 2020 to “preserve its liquidity, at a time when diamond pricing was impacted by the COVID-19 pandemic”. Operations resumed in Q1 FY 2022.
62.7-carat fancy pink diamond “Boitumelo” in Botswana
Lucara keeps raking in the big diamond finds, this time recovering a 62.7-carat fancy pink diamond from its Karowe mine in Botswana.
It is the largest fancy pink gem to found in Botswana, according to the diamond miner, and one of the largest rough pink diamonds on record in the world.
The stone has been named “Boitumelo,” which means joys in Setswana.
Measuring 26 x 17 x 16 mm, it is described as a high-quality fancy pink Type IIa gem.
Lucara uncovered it from the direct ore milling at the EM/PK(S) unit of the South Lobe, the site of many of its biggest finds.
The company said a 22.21-carat fancy pink gem of similar quality was found during the same production period, as were two more pink gems of similar color weighing 11.17 carats and 5.05 carats.
Asked if those additional small pink diamonds could’ve broken off from the same piece as the 62.7-carat diamond, a company spokesperson said: “As the diamonds all came from a similar production period it may be possible, but we cannot confirm this at this time. Further detailed analysis needs to be carried out to confirm if they did indeed originally stem from one diamond.”
Regarding the find, CEO Eira Thomas said, “Lucara is delighted to announce another historic diamond with the recovery of the Boitumelo, and very pleased to demonstrate the continued potential for large, colored diamonds from the South Lobe production.
“These remarkable pink diamonds join a collection of significant diamond recoveries in 2021 produced from the EM/PK(S), which forms a key economic driver for the proposed underground mine at Karowe.”
A 21.86 carat natural pink diamond named “The Pink Palesa” will be sold by the Bonas Group in Antwerp in July.

The pink gem was discovered on May 18 at the Kao mine in Lesotho one of the few sources of pink diamonds in the world following the closure of the iconic Argyle mine last year. Argyle provided about 90% of the world’s pink gems. Kao is operated and owned by Namakwa through its subsidiary, Storm Mountain Diamonds.
According to the report, Kao has yielded several pink diamonds in the last few years: The 25.97 carat Pink Dawn (2021), the 36.06-carat Pink Storm sold in 2014, the 3.06 carat Purple Princess (2017) and the 29.59 carat Rose of Kao (2018).

A 15.81 carat Sakura diamond, the largest of its kind to ever appear for sale, will go under the hammer at Christie’s upcoming Hong Kong Magnificent Jewels Live Auction on May 23, the auction house announced on Tuesday. Estimated at $25 million to $38 million, the “fancy vivid purple pink internally flawless” diamond will be the star highlight of the sale.
It is the diamond’s exceptional rarity, extraordinary optical transparency, brilliant colour, and enormous size that make it an immensely important, and eternal masterpiece of nature.
As fewer than 10 per cent of pink diamonds weigh more than one-fifth of a carat, this fancy vivid purple-pink diamond is of an unprecedented size of 15.81 carats, which is the largest of its kind Fancy Vivid Purple Pink to be offered at any auction.
It added that the lot fell in the exclusive group of the four per cent of pink diamonds that possess a colour deep enough to qualify as “fancy vivid”.
This magnificent gem is graded ‘fancy vivid’ for its perfect display of strong saturation and remarkable pink hue with a secondary colour of purple, resembling the fascinating colour of cherry blossoms – appropriately coinciding with spring.
