Coloured diamonds outshine whites as top mine’s sparkle fades

Pink and violet stones surge in value amid uncertainty over site where 90% are found.

Over a quarter of a century Larry West has scoured the globe looking for some of the world’s rarest coloured diamonds. This week he secured a big prize, the Argyle Violet, which he bought along with 15 other coloured stones for more than $10m.

“At 2.83 carats, this is the largest and most valuable violet diamond ever recovered from the Argyle mine,” says Mr West, founder of New York’s LJ West Diamonds. “You could fill a garbage truck with the rough diamonds produced from the mine every year, an ashtray with pink diamonds but only a half teaspoon of violets,” he says.

Rio Tinto’s Argyle mine, which is based in the remote north-west of Australia, produces about 90 per cent of the top-quality red, pink and violet diamonds dug up worldwide. The stones are extraordinarily rare, accounting for 0.1 per cent of the mine’s annual output with the remainder made up of more affordable champagne and cognac stones used in the fashion jewellery sector in the US, China and India.

Uncertainty over the Argyle mine’s future, as well as growing appreciation for rare pink diamonds among the super-rich, is prompting a surge in the value of these coloured stones even as the price of traditional white diamonds falls on world markets.

A 9.14 carat pink pear-shaped diamond is expected to realise $16m-$18m when it is auctioned at Christies in Geneva next week.

“Pink diamond prices have tripled over the past 15 years and on average would be at least 25 to 30 times the value of white diamonds,” says David Fardon, chief executive of Linneys, one of 35 ateliers mandated to buy coloured diamonds from Argyle.

By comparison, global sales of diamond jewellery fell in 2015 for the first time in six years, declining 2 per cent to $79bn. Sales of rough diamonds fell 30 per cent.

Mr Fardon says the scarcity of coloured pink, red and violet diamonds mined at Argyle has enabled them to buck the downward trend in diamond prices. He says they have become a collectable item, with some of his clients buying the stones to include as part of their retirement savings fund.

Prices are rising 15 per cent a year because of increasing awareness of rare coloured diamonds, growing demand from China and India and the fact production at the Argyle mine is only guaranteed until 2020, says Mr Fardon.

In 2013 Rio said it was extending Argyle’s life until 2020 by building an underground extension to the existing open-cut mine. But it is uncertain whether Rio will sanction any new investment to extend the Argyle mine’s life beyond that date, in part because the valuable pink diamonds make up a small fraction of the mine’s total output.

“The odds are the mine will close a year or two after that, which means these stones will become more and more valuable,” says Mr West, one of the world’s most prodigious buyers’ of Argyle pinks.

Rio would not comment on its future investment plans for Argyle.

Eden Rachminov, an Israeli diamond specialist and author of The Fancy Colour Diamond Book, says the success of Argyle’s pink diamonds is also down to smart marketing.

“Argyle has done a terrific job in branding its stones, which tend to be more expensive than pink diamonds mined elsewhere in the world such as Russia, Africa and Brazil,” he says.

Celebrities such as Barbra Streisand, Victoria Beckham, Nicole Kidman and Princess Mary, the Australian who married the Danish crown prince, all own Argyle pinks, which are building a loyal following among the rich and famous.

Mr West says he plans to show the Argyle Violet in an exhibition at the Museum of Natural History in Los Angeles to raise awareness of coloured diamonds.

“It’s important to let the public see them and get the word out. That can only add value to the market,” he says.

Christie’s 19ct. Pink Legacy Fetches $50M

Harry Winston bought a pink diamond for more than $50 million at Christie’s Magnificent Jewels sale in Geneva, setting a world auction record.

The rectangular-cut, 18.96-carat, fancy-vivid-pink stone went for $50.4 million at the auction Tuesday, becoming the most expensive pink diamond Christie’s has sold, the auction house said. At $2.7 million per carat, it also achieved a world-record average price for a pink diamond at auction, beating the 14.93-carat Pink Promise, which fetched $32.5 million ($2.1 million per carat) at Christie’s Hong Kong in 2017.

The buyer renamed the stone — formerly the Pink Legacy — as the Winston Pink Legacy. It previously belonged to the Oppenheimer family, and had a presale estimate of $30 million to $50 million.

“This exceptional diamond captured the imagination of international collectors across the globe, with over 30,000 people visiting Christie’s sale previews to see this remarkable stone,” said Rahul Kadakia, Christie’s international head of jewelry. “It has taken its rightful place among the world’s greatest diamonds.”

The auction also saw an Art Deco piece by Van Cleef & Arpels fetch $4.3 million, well above its presale estimate of CHF 2 million to CHF 3 million ($2 million to $3 million). A natural-pearl necklace garnered $1.2 million against a valuation of CHF 240,000 to CHF 340,000 million ($238,190 to $337,345 million).

Some 86% of lots sold at the Magnificent Jewels auction, yielding a total of $110.2 million. The event was 90% sold by value of items available.

‘As good as it gets’ — The Pink Legacy diamond

Rahul Kadakia, International Head of Jewellery at Christie’s, explains why this spectacular 18.96-carat Fancy Vivid Pink diamond sold for CHF50,375,000 in Geneva.

‘The saturation, the intensity of this stone is as good as it gets in a coloured diamond,’ states Rahul Kadakia, International Head of Jewellery, of the Pink Legacy, an extraordinary 18.96-carat Fancy Vivid Pink diamond that sold for CHF50,375,000 in the Magnificent Jewels  auction on 13 November at Christie’s in Geneva, and was promptly renamed The Winston Pink Legacy by its new owners, Harry Winston.

‘To find a diamond of this size with this colour is pretty much unreal,’ he continues. ‘You may see this colour in a pink diamond of less than one carat. But this is almost 19 carats and it’s as pink as can be. It’s unbelievable.’

Scientists classify diamonds into two main ‘types’ — Type I and Type II. In the latter, the diamond has a particularly rare, almost homogenous colour. ‘Pink diamonds fall under the rare Type IIa category of diamonds,’ explains the specialist. ‘These are stones that have little if any trace of nitrogen, and make up less than two per cent of all gem diamonds. Type IIa stones are some of the most chemically pure diamonds often with exceptional transparency and brilliance.’

While most pink diamonds exhibit a colour modifier like purple, orange, brown or grey, the Pink Legacy shows no trace of a secondary colour. Its even colour distribution, combined with a balanced saturation, tone and straight pink hue, qualify the 18.96 carat diamond for the coveted ‘Fancy Vivid’ colour grading from the Gemological Institute of America (GIA). Only one in 100,000 diamonds possess a colour deep enough to qualify as ‘Fancy Vivid’, and the Winston Legacy set a new record price per carat for a pink diamond.

‘Pink diamonds of any size and depth of colour have always had a special allure. This 18.96 carat emerald cut pink diamond is amongst the rarest of all gemstones’

Tom Moses, Executive Vice President GIA.

In the Fancy Vivid Pink range, diamonds of more than five or six carats are rarely encountered. In fact, fewer than 10 per cent of pink diamonds weigh more than one-fifth of a carat. In the saleroom, Fancy Vivid Pink diamonds over 10 carats are virtually unheard of — in over 250 years of auction history at Christie’s, only four such stones have ever appeared for sale.

Driven by collector demand and an increasingly limited supply, prices for top-quality large pink diamonds has increased exponentially over the years. This booming market reached an historic level in Hong Kong in November 2017 when Christie’s sold ‘The Pink Promise’, an oval-shaped Fancy Vivid Pink diamond of just under 15 carats, for $32,480,500 — a whopping $2,175,519 per carat. The figure remains the world auction record price per carat for any pink diamond.

This incomparable pink diamond has descended from the Oppenheimer Family and its sale was a major moment in auction history.

Rio Tinto’s Argyle Pink Diamonds Tender delivers record results for pink, red and violet diamonds

The following is a press release from Rio Tinto – 9th November 2018.

Rio Tinto’s 2018 Argyle Pink Diamonds Tender collection of 63 rare pink, red and violet diamonds from its Argyle mine in Australia has delivered another record result reflecting strong global demand for fancy coloured diamonds. These results are also a reflection of Argyle approaching the end of its mine life, with the supply of these extremely rare diamonds becoming even scarcer.

The 2018 collection of the finest pink, red and violet diamonds from the iconic Western Australian mine continued its trajectory of double digit price growth. Sold to an undisclosed buyer, Lot Number 1, the Argyle Muse™, a 2.28 carat Fancy Purplish Red diamond is the most valuable diamond in the Tender’s 34 year history.

Amongst the record breaking diamonds sold in the 2018 collection was Lot 2, the Argyle Alpha™, the largest and most valuable Vivid Pink diamond in the history of the Argyle Pink Diamonds Tender. The Argyle Alpha™ was won by Singapore based Argyle Pink Diamonds partner Glajz THG.

Managing director John Glajz said “I am honoured to be custodian of this record breaking gem, a diamond that embodies the rarity, beauty and provenance of Argyle pink diamonds.”

Over the past 18 years the value of Argyle pink diamonds sold at Tender have appreciated over 400 per cent, outperforming all major equity markets.

Rio Tinto Copper & Diamonds chief executive Arnaud Soirat said “The 2018 Argyle Pink Diamonds Tender was highly sought after with record results that underscore the value of these gems in the history of rare coloured diamonds.”

Matthew Aldridge, chief executive of Gemcut Geneva, a successful bidder on a number of diamonds in the 2018 Tender including Lot 5, the Argyle Odyssey™, a 2.08 carat Fancy Intense Pink diamond said “I have been bidding at the Argyle Pink Diamonds Tender since 1987 and continue to be amazed by the magnificent potency of colour of these unique diamonds from this extraordinary mine. As an avid collector of the world’s finest fancy coloured diamonds I was especially delighted to win the Argyle Odyssey™, a match for another diamond that was sold in the Tender over fifteen years ago.”

Almost the entire world supply of rare pink, red and violet diamonds come from Rio Tinto’s Argyle diamond mine in the remote east Kimberley region of Western Australia. Current estimates indicate sufficient economic reserves at the mine to support production through to the end of 2020.

5ct. Pink Sets World Record at Bonhams

Bonhams has sold a pink diamond for US$583,551 per carat, a world-record price for its colour category, the company reported.

The 5.03-carat, fancy-pink VS1 garnered US$2.9 million at the auction house’s Fine Jewellery sale in London last week. The previous record for a fancy-pink diamond was US$528,021 per carat for a stone sold at Sotheby’s in 2016.

“Large pink diamonds are continuing to increase in value year on year,” said Emily Barber, director of jewellery at Bonhams UK. “They are highly desirable to discerning collectors given their rarity and limited supply.”

The stone’s value lies in its even colour saturation, cut and size, Barber added. It is exceptionally rare to see pink diamonds over five carats on the market, she explained.

Other notable items at the auction included a three-stone ring featuring an old-brilliant-cut, 0.95-carat, fancy-blue diamond surrounded by two marquise-cut, fancy-yellow-orange diamonds weighing 0.51 and 0.56 carats. The piece sold for GBP 168,750 ($218,750), well over its original estimate of GBP 80,000 to GBP 120,000 ($103,704 to $155,556).

Two tiaras also exceeded expectations. A Belle Époque diamond headpiece designed by Spanish royal jeweller Ansorena in the classical Greek meander style achieved GBP 162,500 ($210,650) against a presale estimate of GBP 80,000 to GBP 120,000, while a Hennell Art Deco tiara went for GBP 81,250 ($105,320), beating its valuation of GBP 40,000 to GBP 60,000 ($51,850 to $77,780).

In all, Bonhams sold 89% of the lots available at the auction, bringing in total proceeds of GBP 6.9 million ($9 million).

The next Bonhams Fine Jewellery sale will take place in Hong Kong on November 25.

Diamond price forecasts add a rosy tint to mine closures

With few comparable replacements in the pipeline, supply could peak in next 10 years

Miner Rio Tinto unveiled the largest pink diamond from its Argyle mine in Western Australia this summer. The 3.14 carat “Argyle Alpha”, found in 2015, is part of a package of 63 brightly coloured red and violet diamonds shown to potential buyers in Hong Kong this month.

The stones are becoming ever more scarce as the mine, which upended the heavily controlled diamond market when it opened in 1983, is set to come to the end of its life in 2020.

The closure marks a turning point for the diamond market as there are few comparable replacements in the pipeline. Analysts expect the supply of diamonds to peak within the next 10 years, as demand continues to grow.

“Rio Tinto’s Argyle mine is the world’s only source of these highly coveted pink, red and violet diamonds and we expect considerable interest in this year’s collection,” Jean-Sébastien Jacques, Rio Tinto’s chief executive, said in a statement.

 

“You’re seeing the real significant depletion of the very economic mines” – Paul Zimnisky, Diamond Analytics

He added that the constrained supply will “support significant value appreciation for Argyle pink diamonds”. The tender will travel to New York next month, with bids closing on October 10.

Prices for high-quality pink stones have outperformed those of other diamonds over the past decade because of their rarity, according to Paul Zimnisky of Diamond Analytics in New York. He estimates pink stones account for less than 0.01 per cent of the world’s diamonds by volume — the Argyle mine produces close to 90 per cent of these.

The wider diamond market is expected to feel a squeeze, too, however. RBC Capital Markets forecast last year that total supply would increase 4 per cent  to 145m carats this year “before retreating as older mines begin to reach the end of their lives”.

Giant pink diamond from Christie’s a cut above the rest

A pink diamond weighing in at almost 19 carats is set to go on tour before being auctioned in Geneva and could fetch a record price of between $30 million and $50 million, Christie’s auction house announced on Tuesday.

The rectangular cut Pink Legacy is rated “vivid”, the highest rating for a diamond’s colour, and weighs 18.96 carats, making it the largest fancy vivid pink diamond Christie’s has ever offered for auction.

It was once part of the Oppenheimer collection, Christie’s said, referring to the family who built De Beers into the world’s biggest diamond trader.

“Its exceptional provenance will no doubt propel it into a class of its own as one of the world’s greatest diamonds,” said Rahul Kadakia, international head of jewellery at Christie’s.

Only four vivid pink diamonds of over 10 carats have ever been offered for sale at auction, with a record price per carat set last November when Christie’s Hong Kong sold “The Pink Promise”, an oval-shaped diamond of just under 15 carats, for $32,480,500.

The Pink Legacy will be shown in Hong Kong, London and New York before being auctioned by Christie’s Geneva on Nov. 13.

Rio Tinto to Sell Largest Argyle Vivid Pink

Argyle Alpha

Rio Tinto will offer a 3.14-carat, vivid pink diamond at its 2018 tender, the largest stone of its color in the history of the annual sales event.

The emerald-cut Argyle Alpha (pictured) is one of 63 rare pink, red and violet diamonds — weighing a combined 51.48 carats — featuring in this year’s Argyle Pink Diamonds Tender. It is part of a collection of six “hero” diamonds the miner will offer at the sale.

“Rio Tinto’s Argyle mine is the world’s only source of these highly coveted pink, red and violet diamonds, and we expect considerable interest in this year’s collection,” Rio Tinto CEO Jean-Sébastien Jacques said Thursday. “The combination of strong demand and extremely limited world supply continues to support significant value appreciation for Argyle pink diamonds.”

This year’s tender, which the company has called Magnificent Argyle, also includes the Argyle Muse, an oval-cut, 2.28-carat stone, which is the largest purplish-red diamond ever offered at the tender, and came from a 7.39-carat rough. A second diamond, cut from the same stone, will also be up for sale.

The other hero diamonds include the square-radiant-shaped, 1.29-carat, fancy vivid purplish-pink Argyle Maestro; the princess-shaped, 1.57-carat, fancy dark grey-violet Argyle Alchemy; the Argyle Odyssey, a round brilliant, fancy intense pink stone weighing 2.08 carats; and the radiant-shaped Argyle Mira, a 1.12-carat fancy red.

Rio Tinto will unveil the gems at a world exclusive preview in Sydney, and will also showcase them in Hong Kong and New York. Bidding for the diamonds closes on October 10.

The company held its first Argyle Pink Diamond Tender in 1984.

Pretty in pink: Rio Tinto kicks off one of its last rare diamond sales

Rio Tinto is launching one of its last ever pink diamond tenders as it prepares to shut the only pink diamond mine in the world.

The miner has put 63 of its rare pink diamonds from its West Australian-based Argyle mine up for tender, with prices expected to run to nearly $100 million for the entire lot.

Every year, Rio Tinto selects its best pink diamonds to sell to the world’s wealthiest people, and this year’s auction features the largest ever vivid pink diamond since its sales began in 1984, Rio Tinto’s chief executive Jean-Sébastien Jacques told Fairfax Media.

The largest diamond in the 2018 tender is the Argyle Alpha diamond, weighing 3.14 carats, which was actually uncovered in 2015.

Before it was cut, the Alpha pink diamond weighed 5.88 carats.

While the process of creating regular diamonds is well understood – with diamonds able to be synthetically created – it is not yet known why pink diamonds are pink.

The largest ever pink diamond recovered from the Argyle mine, the Pink Jubilee, weighed 12.76 carats.

Although Rio Tinto has not set a price on Alpha, the record price achieved for a pink diamond was $US2.2 million per carat, potentially valuing Alpha at around $US7.9 million ($10.7 million).

The most expensive gem ever sold at auction was the 59.6 carat Pink Star diamond, sold for $US71.2 million last year.

The buyers are typically the super-wealthy, or luxury jewellery businesses from around the world. They are allowed to bid by invite only.

‘Niche market’

“It’s a niche market, there are very few people who are invited to bid. All the bids will be received before the 10th of October, and at that point, we will disclose who are the winners,” Mr Jacques said.

“Last year’s auction was very good and we expect 2018 to be even better.”

The tender starts in Sydney before moving to Hong Kong and finishing up in New York.

However, this could be one of the last auctions with pink diamonds.

Mr Jacques said the world is about to lose its main supply of pink diamonds as its Argyle mine is approaching the end of its supply. Argyle accounts for about 90 per cent of the world’s pink diamonds, with the remaining 10 per cent being random finds in other diamond mines.

“This is the only mine which has consistently produced these types of diamond,” Mr Jacques said.

“It took only a few billion years to produce them all. The mine has only a few years left, about three years.”

While Rio Tinto is shutting down the Argyle mine, it still operates the Diavik diamond mine in Canada’s frozen far north.

“We like diamonds, which is why we have comprehensive exploration for diamonds. It takes a lot of time and a lot of dedication, and we hope to find a new mine like Argyle, but we have to be patient,” Mr Jacques said.
