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.
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.
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.
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.
Australian Diamond Portfolio is set to showcase a selection of the last pink diamonds to be unearthed in Australia before Rio Tinto closes the Argyle mine in Western Australia.
It is rumoured that final excavation at the Argyle mine will take place on November 2.
Sydney-based Australian Diamond Portfolio will curate a set of pink diamonds as part of The Legacy Collection, with affordable prices ranging from $1000 to $10,000.
Coveted for its distinctive colour and coupled with its rarity, the pink diamond is one of the most elusive gemstones in the world, according to Australian Diamond Portfolio.
“Unlike yellow diamonds, which comprise over 60 per cent of all fancy colour diamonds produced, natural pinks fall into the same category as blues and reds for their extreme rarity,” it added.
“… The richer the ‘pink’, the rarer and more valuable the stone. Nowhere else in the world can you find pinks with such character and depth of colour and vibrance of tone as those from the Argyle mine.
“Even if a new mine was to be discovered in the near future, it would still take a minimum 10-15 years to reach the actual stage of producing diamonds to sell.”
Australian Diamond Portfolio consultant and master diamond polisher David Burger said nobody could say for certain what exactly gave pink diamonds their stunning colour.
“Other diamonds get their colour from chemical impurities that absorb light, however, no similar impurities have been found in pink diamonds, leading scientists to speculate that the colour may be the result of some kind of seismic shock that altered the stone’s molecular structure instead,” he said.
The Legacy Collection will feature three shades of the Argyle pink diamonds, which are pink, purplish pink and pink rosé, with weights ranging from 0.08 to 0.14 carat.
A percentage of profits will be donated to the McGrath Foundation.
ALROSA has sold its 6.21-carat cushion cut fancy intense pink purple diamond to Larry West, a New York-based collector of exclusive pink diamonds.
The stone originates from Yakutia, where it was discovered and polished by ALROSA.
For over 40 years, Larry J. West, the owner of New York’s L.J. West Diamonds, has been searching for an extraordinary natural color diamonds. His collection has been featured in Natural History Museum of Los Angeles County and at auctions worldwide.
“As global production declines, pink diamonds will become rarer and thus more valuable,” West said in a statement.
To establish provenance, the collector received an electronic passport from ALROSA that includes a detailed visual history of the diamond’s extraction and production, as well as information about the craftsman’s background.
As part of the company’s traceability initiative, a short film is automatically generated on ALROSA’s digital platform based on information about each diamond available for purchase.
In September, ALROSA hosted its annual auction of colored stones in Hong Kong and sold over 200 diamonds. All stones sold at the auction were accompanied by a digital passport that contained information about the diamond’s origin.
FANCY PINK DIAMONDS soared 116% in value over the past decade, outpacing blues (81%) and yellows (21%), according to a report by the Fancy Color Research Foundation (FCRF), an Israel-based group that tracks diamond pricing data in the global trading centers of Hong Kong, New York and Tel Aviv.
While the overall index for fancy-color diamonds — across all their brilliant hues — increased by 77% from 2009 to 2019, it was the pink diamond category that stood out in the report.
Market watchers believe that the strength of the pink-diamond segment is attributed to the expected closure this year of the Argyle Diamond Mine, which has been operating in Western Australia for the past 37 years.
“Rio Tinto’s Argyle mine is the first and only ongoing source of rare pink diamonds in history,” said Rio Tinto Copper & Diamonds chief executive Arnaud Soirat in 2019. “With the lifecycle of this extraordinary mine approaching its end, we have seen, and continue to see, unstoppable demand for these truly limited-edition diamonds and strong value appreciation.”
Back in April of 2017, The Pink Star, a 59.6-carat, flawless, fancy vivid pink diamond, shattered the world record for the highest price ever paid for any gem at auction. The hammer price of $71.2 million at Sotheby’s Magnificent Jewels and Jadeite sale in Hong Kong easily surpassed the $57.5 million achieved in May of 2016 by the previous record-holder, the 14.62-carat Oppenheimer Blue diamond.
In November of 2018, the 18.96-carat Pink Legacy was purchased for $50.3 million at Christie’s Geneva, establishing a record per-carat price of $2.7 million for a fancy vivid pink diamond. The previous record holder was the 14.93-carat Pink Promise, which sold at auction for $2.2 million per carat in 2017.
FCRF advisory board member Jim Pounds explained why prices for fancy-color diamonds should remain strong: “From the mining perspective, we are currently experiencing a shortage in high-quality fancy-color rough and we therefore feel quite optimistic about the future.”
Canada’s Lucara Diamond continues to find gem quality, coloured diamonds at its Karowe mine, in Botswana, which in April yielded the 1,758 carat Sewelô meaning “rare find” diamond, the largest ever recovered in the African country.
The Vancouver based miner has now recovered a 9.74 carat blue and a 4.13 carat pink diamond from direct milling of the South Lobe, the area that yielded the famous 1,111 carat “Lesedi La Rona” in 2015.
The announcement comes on the heels of last week’s display of a 123 carat gem quality, top white, Type II diamond, found at the same section of the mine.
It also follows the recent sale of a 2.24 carat blue for $347,222 per carat.
Karowe, which began commercial operations in 2012, has this year yielded 22 diamonds larger than 100 carats, eight of them exceeding 200 carats.
Since the start of the year, the miner has sold 19 diamonds each with an individual price in excess of $1 million at its quarterly tender sales. This includes seven diamonds that fetched more than $2 million each, and one diamond that carried a final price tag of over $8 million.
“Lucara is extremely pleased with the recovery of these rare, sizeable, fancy coloured diamonds, which have the potential to contribute meaningful value to our regular production of large, high-value type IIa diamonds,” chief executive, Eira Thomas, said in the statement.
The precious rocks will be put up for sale in December, during the company’s fourth quarter tender.
Lucara, which has focused efforts on the prolific Botswana mine this year, is close to completing a feasibility study into potential underground production and life of mine expansion at Karowe.
