Lucapa Unearths 170ct. Pink from Lulo

The 170-carat pink diamond.

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.


Rio Tinto Launches Business for Argyle Pinks

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 to sell 32-ct Pink Diamond from Re-opened Mine

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.

Lucara’s 62-Carat Fancy Pink ‘Boitumelo’

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.”

Flawless largest purple-pink diamond expected to fetch over $25 mn at Hong Kong auction

15.81 carat fancy vivid purple pink diamond

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.

Pink Diamond Ring Beats Estimate at Bonhams

The pink-diamond ring from the collection of Joan Collins

A fancy pink diamond ring by Meister was the top seller at the Bonhams London Jewels sale, garnering $1.1 million USD.

The piece, with a step-cut 3.62 carat center stone and designed in 1968 by Meister, exceeded its high estimate of $989,417 USD at the November 12 auction, Bonhams said last week. 

A diamond brooch from the collection of Dame Joan Collins, designed by Van Cleef & Arpels, fetched $161,892 USD, more than six times its high valuation. It was part of a collection of the actress’s jewels that saw 100% of items find buyers, with the final sales total three times higher than the auctioneer had estimated. A portion of the proceeds from Collins’s jewelry will be donated to the Shooting Star Children’s Hospice, of which she is a patron.

Other notable items at the auction included a sapphire and diamond ring, which fetched $189,865 USD against a high estimate of $131,851 USD, and a three-stone diamond ring, which brought in $132,179 USD, nearly doubling its estimate.

In total, the auction achieved $5 million USD, with Bonhams selling 75% of items on offer.

“Despite the auction taking place behind closed doors, the bidding remained spirited and the results demonstrate that high quality pieces with extraordinary provenance continue to captivate buyers around the world,” said Jean Ghika, global head of jewelry for Bonhams.

$27M Pink Diamond Sets Record at Sotheby’s

The Spirit of the Rose diamond.

Alrosa’s Spirit of the Rose has achieved the highest price for any purple-pink diamond, selling to an anonymous bidder for nearly $27 million at Sotheby’s Geneva.

The oval modified brilliant-cut, 14.83-carat, fancy-vivid-purple-pink, internally flawless, type II stone, named for the famous Russian ballet, sold for $26.6 million, beating its low estimate of $23 million. The diamond, which fetched $1.8 million per carat, led the Magnificent Jewels and Noble Jewels live auction Wednesday, which garnered $52.2 million in total, Sotheby’s said.

The purchase comes on the heels of the recent closure of Rio Tinto’s Argyle mine in Australia, which produced more than 90% of the world’s pink diamonds. Prices for stones of that color are likely to soar in the coming years, experts have noted.

“The Spirit of the Rose caught the imagination of everyone who had the chance to see it,” said Benoit Repellin, head of the Sotheby’s Geneva Magnificent Jewels auction. “With its size, beautiful color, perfect cut and oval shape, it is a wonder of nature, steeped in Russia’s century-long diamond tradition and cultural heritage. It fully deserves the price achieved tonight, which is also testament to the growing appreciation and awareness of the great scarcity of pink diamonds around the world.”

Sotheby’s also saw strong prices for white diamonds at the auction, with 10 out of 11 stones on offer selling above their estimates. A cushion-shaped, 18.03-carat, D-color, flawless, type IIa diamond fetched $1.9 million against a high estimate of $1.1 million, while a pear-shaped, 102.41-carat, light-brown diamond of VVS2 clarity brought in $1.3 million, exceeding its high valuation.

Noble jewels were in demand as well, Sotheby’s said, led by a Colombian emerald and diamond parure from the collection of the first Marquis de Guirior, viceroy of New Granada and viceroy of Peru. That piece also surpassed its high estimate, fetching $1.1 million.


Rio Tinto closes Argyle diamond mine after 37 years


Pink diamonds, already rare, are about to get scarcer as Rio Tinto has closed its iconic Argyle diamond mine, the world’s biggest and the main global source of high-quality pink diamonds.

Since opening its doors 37 years ago, the Western Australia mine produced 865 million carats of rough diamonds and became the source of about 90% of the world’s prized rose-to-magenta hued stones.

The Argyle ore body, a single pipe known as AK1, was discovered in October 1979. Alluvial operations began in 1983, open pit mining kicked off in 1985 and the mine became a fully underground operation in 2013.

Today, Rio has mined the very last of these unique diamonds from the site, located within the ancient Matsu Ranges more than 3,000 km north of Perth.

“Fifty years ago there were very few people who believed there were diamonds in Australia even fewer could have foreseen how the Argyle story would unfold,” Rio Tinto’s chief executive of Copper and Diamonds, Arnaud Soirat, said in a statement.

“To arrive at this final chapter has required vision, courage and determination to overcome significant challenges to enter new territory in diamond exploration, mining and marketing,” Soirat added.

The closure of Argyle will remove about 75% of Rio’s diamond output, yet the impact on the miner’s earnings will be negligible. Diamonds bring in only about 2% of its earnings, while iron ore the company’s main commodity accounts for almost 60%.

The operation will now undergo decommissioning and rehabilitation, which is expected to take five years. After that, Rio will monitor the site for a period yet to be defined.

End of an era

Andrew Wilson, general manager of Argyle, said the mine transformed the diamond sector since its opening, supplying gems for both ends of the market.

“A new chapter will now begin as we start the process of respectfully closing the Argyle mine and rehabilitating the land, to be handed back to its traditional custodians,” he said.

Argyle was Australia’s first large-scale diamond operation, pioneering the fly–in fly–out model, and seen as an opportunity for a workforce drawn from across the nation.

Rio Tinto closes Argyle diamond mine after 37 years
Forty years ago, in the Kimberley region of Western Australia, four diamonds in a dry creek bed ultimately led Rio’s geologists to a massive diamond deposit.

It also triggered the creation and adoption of new technology and exploration methods to make the search for diamonds more efficient across the rugged and remote Kimberley landscape.

At its peak, Argyle churned out 40% of the world’s diamond output, which made it the biggest producer by volume.

Pricy gems

Analysts and auctioneers alike expect prices for pink diamonds to go up and, potentially spur exploration.

Pink stones have already been fetching record prices in the past few years and the closure of their main source could see that trend strengthen.

The “Pink Star” went for $71.2 million at Sotheby’s Hong Kong in April 2017, setting a record for diamonds sold in auctions.

In 2018, the 18.96-carat Pink Legacy fetched $50 million at Christie’s auction house, breaking the world record for price paid per carat for a pink diamond at auction.

At Sotheby’s Hong Kong 2019 sale, one of the star pieces described as an “exquisite 10.64 carat vivid purplish pink diamond” sold for just under $20 million.

Rio Tinto’s own data show that prices for their Argyle pink diamonds jumped by 500% from 2000 to earlier this year.
