Sotheby's sells pink, blue diamond earrings for about $51M

ABC News - Sotheby's sold a pair of pear-shaped diamond earrings at a hammer price of about $51 million Tuesday, though the 14.54-carat flawless Fancy Vivid Blue diamond that was the auction's highlight fell short of the expected range.

Sold as separate lots, the "Apollo Blue" and "Artemis Pink" diamonds together cracked the low end of the expected range of $50 million to $70 million, but were a record for earrings sold at auction, Sotheby's said.

The earrings were the standout offerings at a Geneva auction of nearly 400 pieces of jewelry that reaped more than $150 million altogether.

At the hammer price, excluding fees, the Apollo Blue — the largest internally flawless Fancy Vivid Blue ever sold at auction — went for 37 million Swiss francs ($37.5 million), Sotheby's said. The total cost was $42.1 million, including the "buyer's premium."

Auctioneer David Bennett, chairman of Sotheby's international jewelry division, called that a "very healthy price."

The matching, 16-carat pink diamond went for a hammer price of about $13.5 million. Overall, the pair went for a total, including fees, of more than $57 million.

Bennett declined to identify the buyer who snapped up both lots, but the auction house did say the buyer was renaming the gems as "The Memory of Autumn Leaves" for the blue diamond earring and "The Dream of Autumn Leaves" for its pink sister.

Sotheby's sold a pair of pear-shaped diamond earrings at a hammer price of about $51 million Tuesday, May 16, 2017, though the 14.54-carat flawless Fancy Vivid Blue diamond that was the auction's highlight fell short of the expected range.

'Pink Star' diamond sells for record $71.2 million at auction

It took nearly two years to cut the Pink Star from a rough diamond. It first appeared in public in 2003 and later became part of an exhibit at the Smithsonian National Museum of Natural History, home of the famous 45.52 carat blue Hope Diamond. It was also displayed at the Natural History Museum in London.

Tuesday's winning bid surpassed the previous world auction record for a pink diamond -- $46.16 million for the 24.78 carat Graff Pink, sold at Sotheby's in Geneva in 2010.

Chow Tai Fook has renamed its new possession the CTF Pink Star in memory of the company's founder and to commemorate the brand's 88th anniversary.

A diamond as rare as you.

For centuries, natural color diamonds have been regarded as the world’s most sought-after gems, from collectors to royalty. Diamonds so rare that they are only discovered in a few locations on earth, they are likened to works of art, hidden treasures and rare books.

One of the exciting factors involved in natural color diamonds is the origin of how they get their unique colors, where they are found and why they are so unique.

Rare Multi-Color Diamonds part of the L.J. West Diamonds collection.

• Tiny amounts of nitrogen created yellow and orange shades.
• The element boron created blues.
• Hydrogen causes the color violet to appear.
• Tremendous pressure occasionally would realign or spiral the diamond’s crystal structure, creating red, pink, purple and brown diamonds.
• Millions of years of natural radiation produced green diamonds.

Color diamonds have been around since the beginning of diamonds discovered approximately 3000 years ago in India; it is only the last decade where the desire and appeal for them have entered the consumer market. The growing awareness of rarity and value have created increased demand for natures most special diamonds At auction natural color diamonds are exceeding record prices with the 14.62 carats Oppenheimer blue diamond selling for an impressive $57,541,779 USD at Christie's in May of 2016. This blue diamond was the largest vivid blue diamond ever to sell at auction and holds the current record for highest price paid for any jewel at auction.

In 2014, the 12.03 fancy vivid blue “Blue Moon of Josephine” diamond sold for $48.4 million and still holds the current price per carat record for any public sale at auction at $4 million per carat. In 2015, a collector paid US$28,523,925.00 for a 16.08 Fancy Vivid Pink Diamond, setting a new world record for the highest price paid and highest price paid per carat at $1.773,875.00 for a Fancy Vivid Pink diamond.

These values highlight the exceptionally rare stones but are proven examples of the desirability for them.

Any buyer or collector has a spectrum of color to select from in natural colored diamonds, and there is no right or wrong in choosing what diamond can appeal to your taste. Prices for natural color diamonds can start from $100 up to $1 million per carat plus, the characteristics in determining a stones value can vary with the exceptionally rare stones being valued by rarity, size and color. However, the main reason to own any is all the same – beauty, is the ultimate reason to own a natural color diamond!

A natural color diamond is as rare as you, no color is the same and no diamond is alike. The diamonds can be compared to the endless variety of flowers on our earth, a colorful rainbow in the sky and the unique personalities found all around the world.

Consider finding a color diamond that is as distinctive and alluring as you are. You will not be disappointed in your quest to do this.

Why 2016 was the year of the colored diamond

By Nick Glass, CNN

Updated 5:27 AM ET, Tue December 20, 2016

(CNN) Relatively small, but slowly and perfectly formed over billions of years, the Argyle Violet diamond is so rare in color that it has its own unique diamond classification: "Fancy Deep Grayish Blueish Violet."

It was "a once in a lifetime discovery. I fell in love with it. We had to have it," says Scott West of L.J. West Diamonds Inc. of New York.

Like his father, Larry, and his grandfather Max before him, West is a diamond hunter, searching for the rarest and most unusually colored stones.

His most recent acquisition, the 2.83-carat oval Argyle Violet is being displayed as part of "Diamonds: Rare Brilliance" at the Natural History Museum of Los Angeles County.

An exclusive offer

Scott West spends three months every year traveling the world looking for special stones.

The Argyle Violet came from the remote Argyle Mine in North West Australia. Every year for the last 30 years, the mine's owner, Rio Tinto, has invited a select group of buyers to tender for newly discovered stones by sealed bid. It's said to be the most exclusive diamond sale in the world.

This year, there were 63 diamonds on offer, all pink, red or violet.

West says he and his father, Larry, first saw the Argyle Violet in a secure room in Hong Kong in September, and made "multi visits in differing light" before placing their bid in November.

He declined to comment on a Financial Times report that L.J.West's winning bid was more than $10 million for the Argyle Violet and 15 other colored stones, although he did agree that it was "tough" having to make a sealed bid.

The allure of the sparkle

L.J. West claims to have the largest inventory of large colored diamonds in the world with some 2000 stones of all colors, many of them pink.

But, naturally, West remains discreet about money and collectors. Though the company did admit that Halle Berry wore one of their diamond rings (the Pumpkin Diamond, Fancy Vivid Orange, 5.54 carats) when she won her Oscar in 2002.

"The Middle East is a strong market. China continues to grow. The United States is still the strongest market of all," he says.

IN DIAMONDS: RARE BRILLIANCE AT THE NATURAL HISTORY MUSEUM OF LOS ANGELES COUNTY

New York, November 28, 2016 — The Natural History Museum of Los Angeles County (NHM) today announced details for its coming exhibition Diamonds: Rare Brilliance, which will bring together rare colored gems never before seen in the United States inside the museum’s renowned Gem and Mineral Hall. At the center of Rare Brilliance will be the “Juliet Pink Diamond,” which is an extremely rare pink diamond of over 30 carats, and a Fancy Deep Grayish Bluish Violet named the “Argyle Violet” after the eponymous Argyle mine in Western Australia, where it was discovered in 2015. Through stunning examples, such as the fluorescent lighting of a “rainbow” diamond necklace and a very rare Victorian Orchid Vivid Purple diamond, the exhibition will bring to light the rare properties of colored gemstones, the science behind natural colored diamonds, and how the interplay of light and chemistry gives diamonds color. Organized in partnership with L.J. West Diamonds, Rare Brilliance will be on view from December 16, 2016, through March 19, 2017.

“We are thrilled to share these gems, which are incredibly rare in color, intensity, quality and size — and so brilliantly fashioned from the original roughs — with museum visitors, providing opportunities to learn about the geology, physics and chemistry behind each diamond’s sparkle and hue,” said Dr. Aaron Celestian, NHM’s Associate Mineralogy Curator. “These jewels, on loan from L.J. West, capture the imagination and will shine amongst the museum’s world-renowned collection of gems and minerals.”

“Throughout history diamonds have been synonymous with love and romance. The Juliet Pink captures this connection with its vibrant, strong pink color that is both alluring and seductive. After understanding the stone’s importance and color we decided to name the stone the ‘Juliet Pink Diamond,’ as the stone captivates passion and ultimate beauty.” – Scott West, the vice president of L.J. West Diamonds.

The Juliet Pink Diamond, which will be set in a necklace with marquise, pear and round-cut white diamonds totaling 98.70 carats for the exhibition, has been designated a type IIa diamond by the Gemological Institute of America (GIA) for its remarkable chemical purity and clarity. Natural colored diamonds are a strikingly rare phenomenon, occurring in an estimated one out of every 10,000 gems, and the precise science behind individual colors remains a mystery.

In addition to the Juliet Pink Diamond, Diamonds: Rare Brilliance will introduce U.S. audiences to one of the world’s rarest diamonds — a Fancy Deep Grayish Bluish Violet named the “Argyle Violet” after the Argyle mine in Western Australia. There are no other known diamonds of this combination of colors or with the same clarity and size, and it is the largest Violet to be discovered in the Argyle Diamond Mine. The 9.17 original rough stone was an unusual shape characterized by deep grooves and an uneven surface. After more than 80 hours of carving and polishing, the diamond on view in NHM’s Gem Vault is a 2.83-carat oval that is set in a designer ring surrounded by Argyle Vivid Pink Diamonds.

West Diamonds said. “Just as the ring and necklace settings provide a backdrop to highlight the brilliance of the cut stones, the excellent company of NHM’s Gem and Mineral Hall collection will provide the perfect context for these rare and important diamonds.”

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. 

The Argyle Diamond Mine in Western Australia

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. 

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.

The Company that Bought the Violet Diamond

By Michelle Graff - National Jeweler

So is violet the rarest hue of diamond there is? “There’s no question about it,” said Larry West of L.J. West Diamonds, the company that placed the winning bid on this 2.83-carat violet diamond from the 2016 Argyle tender.

New York--It’s the biggest violet diamond ever found at Australia’s Argyle Mine, and it now belongs to a New York company that’s been in the colored diamond business for nearly 40 years.

L.J. West Diamonds Inc. placed the winning bid on the 2.83-carat “Argyle Violet,” the centerpiece of this year’s Argyle Pink Diamonds Tender, Rio Tinto’s annual sale of the top diamonds to come out of its Argyle mine.

Company President Larry West said the Violet, a diamond that generated a lot of interest and excitement, was a stone he “really wanted to possess.”

“There’s such a huge disparity between this size and the next biggest violet stone that’s ever come out of the (Argyle) mine,” he said, referencing the 1.41-carat Ocean Seer from the 2008 tender. “It’s such a rarity that I felt it was worth bidding on.”

West is not saying how much he paid for the stone, which is being set in a ring and surrounded by smaller Argyle pinks, though he did reveal that it will be available to purchase next year.

But he won’t be taking the violet diamond to Christie’s or Sotheby’s to sell it.

Rather, L.J. West Diamonds will offer the Argyle Violet through its network of retail partners after it is featured in the “Diamonds: Rare Brilliance” exhibition slated to run from December to March 2017 at the Natural History Museum of Los Angeles County.

“I am glad to have it shown,” West said of the violet’s inclusion in the exhibition. “It’s so rare. Nobody’s ever seen stones like this, and I think it’s important for them to be out there in the public domain. It makes it more real for people; it’s not just a story.”

This year, a total of 63 pink, red and violet diamonds--collectively dubbed “The Chroma Collection”-- comprised the Argyle tender, which was 100 percent sold by lot.

Collectively, the stones represented the highest quality, size and color composition in the tender’s 32-year history and, consequently, achieved the highest average price per carat ever.

Beyond L.J. West Diamonds, Rio Tinto did not reveal the names of any companies that purchased a diamond from the tender, nor did it share prices.

Blue diamonds have been stealing the spotlight as prices skyrocket.

Blue Diamonds have become celebrities on the auction scene with all the attendant fame. The fan fare continues this month with an 8.01-carat fancy vivid blue diamond ring by Cartier, named The Sky Blue Diamond, set to be auctioned at Sotheby’s Geneva. But what accounts for the soaring interest and stratospheric prices that these diamonds command in today’s market? From gemologists to diamond brokers to the heads of jewelry sales at the two major auction houses and an industry expert, the answer can be summed up in two words: extremely rare.

A rare Natural Intense Blue Diamond set in a white diamond necklace by Scott West by L.J. West Diamonds

““more and more people are discovering the beauty of a blue diamond,” ”

— Larry West

“There is so much more buzz now. There is more awareness of how rare these diamonds are,”explains Larry West,president of L.J.West Diamonds, a color diamond specialist based in New York City. “Previously, information about these exotic stones was only available to the most involved collectors.But now there are more discussions within the high-end jewelry trade.”And while collectors might consider a blue diamond the ultimate investment, “more and more people are discovering the beauty of a blue diamond,” says West, who admits to being“passionate”about these diamonds.

“Perhaps one in 10,000 exhibits any color. A diamond with any evidence of blue color—even if the color is very faint—is less than one-tenth of 1 percent of what would be mined in one year.” Historically, some blue diamonds were discovered in the Golconda region in India; the Hope Diamond has been traced to that area.However, the only source to produce a very small but consistent supply of blue diamonds is the Cullinan Mine in South Africa,owned by Petra Diamonds.

Rio Tinto’s Argyle Pink Diamonds Tender delivers record result 7 November 2016

Rio Tinto’s spectacular 2016 Pink Diamonds Tender collection of 63 rare pink, red and violet diamonds from its Argyle mine has delivered a record result, reflecting strong global demand for these increasingly rare diamonds. Known as The Chroma Collection, the 2016 Argyle Pink Diamonds Tender comprised the highest quality, size and colour composition in the Tender’s 32 year history and was highly sought after, with winners from 10 countries including a strong representation from the sophisticated US collector market.
The 2016 Argyle Pink Diamonds Tender achieved the highest average price per carat since the Tender began in 1984.

Rio Tinto Diamonds general manager of sales Patrick Coppens said “We are delighted with the results of this year’s historic collection. Argyle’s pink, red and violet Tender diamonds are in a class of their own in terms of rarity, beauty and provenance. These natural coloured diamonds are truly beyond rare.”

The 2.83-carat Argyle Violet, is the largest and most valuable violet diamond recovered to date from the Argyle mine

The dazzling centrepiece of the collection, the 2.83-carat Argyle Violet, is the largest and most valuable violet diamond recovered to date from the Argyle mine in the remote east Kimberley region of Western Australia. The Argyle Violet was secured by US based coloured diamond specialist, L.J. West Diamonds Inc, which plans to showcase the historic diamond at the Diamonds: Rare Brilliance exhibition at the Natural History Museum of Los Angeles County in December 2016. President of L.J. West Diamonds Inc Larry West said “The Argyle Violet is an incomparable diamond that forms an important addition to our Art of Nature collection of rare gems. It is a truly unique treasure that we are proud to be exhibiting as one of the finest examples of a historic fancy colour diamond.”

Over the past 15 years the value of Argyle pink diamonds sold at Tender have appreciated over 300 percent. Argyle Pink Diamonds manager Josephine Johnson said “The market fundamentals for pink diamonds -strong demand as a result of extremely limited supply - continue to support their significant value appreciation.“

Rio Tinto’s Argyle mine produces virtually the entire world’s supply of rare pink diamonds, with the finest from a full year’s production showcased in the annual Argyle Pink Diamonds Tender.

The 2016 Tender was the first to comprise diamonds solely from Argyle’s underground mine.

Rio Tinto’s Argyle Pink Diamonds business has unveiled the largest violet diamond recovered from the Argyle mine in Western Australia.

The 2.83 carat polished oval shaped diamond, known as The Argyle Violet, will be the dazzling centrepiece of the 2016 Argyle Pink Diamonds Tender, the annual showcase of the rarest diamonds from the Argyle mine.

The Argyle Violet

Argyle Pink Diamonds manager Josephine Johnson said “We are very excited to announce this historic diamond ahead of our Tender launch. This stunning violet diamond will capture the imagination of the world’s leading collectors and connoisseurs.”

More than 90 per cent of the world’s rare pink diamonds come from the Argyle mine and it is the only source of hydrogen- rich violet diamonds. Violet diamonds are seldom seen and in 32 years Argyle has produced only 12 carats of polished violet diamonds for its iconic Tender.

The Argyle Violet was polished in Western Australia by one of Argyle’s master polishers, Richard How Kim Kam, from a 9.17 carat rough diamond discovered in 2015. The Argyle Violet has been assessed by the Gemological Institute of America (GIA) as a notable diamond with the colour grade of Fancy Deep Greyish Bluish Violet.
