Vivid green brilliant diamond sale sets two new world records in Hong Kong

Two world records have been set by a fancy vivid green 5.03 carat diamond on Tuesday at Christie’s Hong Kong Magnificent Jewels sale, selling for $US16.8 million (AUD$23 million).

The rectangular cut diamond, dubbed “Aurora Green”, was purchased by Hong Kong’s Chow Tai Fook Jewellery, one of the largest jewellery retailers in the world.

The sale set a world auction record as well as a world record price per carat for a green diamond, Christies said.

Aurora Green was one of four lots at the auction that set new world records; others included US$7.2 million (AU$9.9million) for a Kashmir sapphire bracelet, US$11.6 million (AU$16million) for a pair of ruby ear pendants, and US$967,000 (AU$1.3million) for a jadeite pendant necklace.

A total of US$85 million (AU$117 million) was achieved during the week of sales.

Pink diamond sells for world record price

A pink diamond that was first cut in the 1920s has reached a world-record sum at auction.

Categorised as fancy vivid pink, the 18.96-carat diamond, named Pink Legacy, reached 50.3 million Swiss francs ($68.8 million) at the Magnificent Jewels auction run by Christie’s in Geneva, Switzerland. This priced the diamond at around $3.6 million per carat.

This pink diamond had been estimated to sell for between $US30–50m ($41–69 million) at auction.

It was discovered in South Africa and was previously possessed by the former owners of De Beers.

Christie’s has referred to the Pink Legacy as the “largest fancy vivid pink diamond ever offered” at any of its diamond auctions.

Pink Legacy is a Type IIA diamond, which are chemically very pure with little to no nitrogen content. This category accounts for less than two per cent of all gem diamonds worldwide.

The diamond was purchased by American jewellery company Harry Winston, which has dubbed it the Winston Pink Legacy.

Australia is well-known for the production of pink diamonds at the Rio Tinto-run Argyle mine in the Kimberley region of Western Australia.

The company broke records with two diamonds at a tender earlier this week that saw the sale of 63 rare pink, red and violet diamonds from the mine.

Alrosa prepared to now auction the most expensive diamond ever polished in Russia

Part of its “Dynasty collection,” consisting in five diamonds polished from a 179-carat rock found in 2015

Russian miner Alrosa  (MCX:ALRS), the world’s top diamond producer by output will auction Wednesday a rare collection of diamonds produced domestically, including the most expensive rock ever polished in the country — a giant 51.4-carat gem.

More than 130 potential buyers have already registered to participate in tomorrow’s online sale of the diamond collection, named after the dynasties of the Romanov, the company said in a statement. That family ruled for more than 300 years before the Russian Revolution.

The largest of all bears the same name as the entire Dynasty collection. It’s a huge, traditional round-cut diamond, whose 2.5 cm (1 inch) diameter is equal in size to the visible part of a human eye.

Discovered in 2015, the rough version of the diamond was a massive 179-carat gem, found in a mine in the northeast region of Sakha. It was then cut and polished into five smaller gems, named after noble families of the imperial era: Sheremetyev, Orlov, Vorontsov and Usupov.

“There was a good reason to choose the name for the collection, which is connected with Alrosa’s intention to revive the traditions and memory of renowned Russian jewelers famous for their craftsmanship and filigree since Russia’s first cutting and polishing factory founded by Peter I (the Great) early in the 18th century,” the company said.

According to Alrosa, the Dynasty diamond is potentially the most expensive diamond manufactured in the history of Russian jewellery because of its quality.

Alrosa’s decision to produce these polished diamonds and sell them online fits with a broader industry quest to find new ways to the market and add value on the part of gem producers.

Alrosa and Anglo American’s De Beers unit, which for the first time auctioned polished stones this year, produce about half of the world’s rough diamonds.

Lucara sells world’s second-largest diamond for $53 million

The tennis ball-sized Lesedi La Rona rough diamond that Lucara Diamond (TSX:LUC) unearthed two years ago at its Karowe mine in Botswana was sold this week for $53 million.

The buyer, London-based Graff Diamonds, paid nearly $47,777 per carat.

“The stone will tell us its story. It will dictate how it wants to be cut, and we will take the utmost care to respect its exceptional properties,” said the gem’s new custodian, Laurence Graff, in a press release.

On the other hand, Lucara CEO William Lamb stated that Graff paid a fair price for the 1,109-carat diamond, whose discovery marked a defining moment for the Vancouver-based company.

Such finding, he said, “solidified the amazing potential and rareness of the diamonds recovered at the Karowe mine. We took our time to find a buyer who would take the diamond through its next stage of evolution.”

Pink Star diamond sets new world auction price record in Hong Kong

 

A rare diamond known as the Pink Star has been sold in Hong Kong for more than $71m (£57m), setting a new world record for any gemstone at auction.

The oval-shaped 59.6 carat stone was bought after just five minutes’ bidding at Sotheby’s, reports said.

It is the largest polished diamond in its class to go under the hammer.

It sold for $83m in Geneva in 2013 but the buyer later defaulted. The record until now was held by the Oppenheimer Blue, which sold for $50m last May.

Bidding for the gem, which was found by De Beers at a mine in Africa in 1999 and cut over a period of two years, began at $56m.

Sotheby’s said the buyer was Hong Kong jewellery retailer Chow Tai Fook Jewellery.

Alexander Breckner, head of diamonds at jewellers “77 Diamonds”, told the BBC that the stone was exceptional.

“It’s the largest pink diamond ever found in the history of humankind. It’s an incredible colour to it.

“And the sheer size of the stone already makes it so rare and so beautiful.”

Previous records set in stone

May 2016: A large diamond known as the Oppenheimer Blue set a new auction record, reaching a price of $50.6m (£34.7m at the exchange rate then current). The 14.62-carat gem was sold after 20 minutes of phone bidding at Christie’s auction house in Geneva. The buyer’s identity is unknown.

November 2015: The Blue Moon, a 12.03-carat ring-mounted blue diamond, caught the eye of Hong Kong tycoon Joseph Lau, who paid a record $48.4m (£31.7m) for the cushion-shaped stone. He bought it for his seven-year-old daughter, renaming it the “Blue Moon of Josephine” after her.

May 2015: An unnamed buyer made history after purchasing the Sunrise Ruby, a 25.59-carat “pigeon blood” coloured gemstone, for $30m (£19.1m). At that price, it became the world’s most expensive precious stone other than a diamond.

November 2013: The “largest vivid orange diamond in the world”, according to Christie’s, attracted the highest price paid per carat for any diamond at auction, selling for $35m (£22m), or $2.4m (£1.5m) per carat.

November 2010: The Graff Pink, a 24.78-carat “fancy intense pink” stone described as “one of the greatest diamonds ever discovered”, auctioned for $46.2m (£29m). At the time it was believed to be the most expensive gemstone bought at auction and was sold to the well-known British dealer Laurence Graff.

De Beers taps into polished diamonds market with first-time auction

Anglo American’s De Beers, the world’s largest rough diamond producer by value, has decided to begin selling its own polished diamonds in auctions for the first time in its history.

The pilot auction, scheduled for June, will include a wide range of polished stones manufactured directly from the company’s own rough diamonds.

The pilot auction, scheduled for June 29, will include a wide range of polished stones manufactured directly from De Beer’s own rough diamonds.All the polished rocks will carry grading reports from both the International Institute of Diamond Grading & Research (IIDGR) — De Beers’ in-house grading unit — and the Gemological Institute of America (GIA).

“We are interested in testing the level of demand from polished buyers for diamonds that have a clear and attractive source of origin, and that offer the assurance of product integrity that dual certification provides,” Neil Ventura, the miner’s executive vice president of auction sales, said in the statement.

If successful, the process would provide De Beers with more insight into the polished market, while also helping consumers fill gaps in supply or inventory if they were unable to find goods at the company’s rough auctions, he added.

All registered De Beers auction buyers will be eligible to bid in the first sale, which takes place on June 29.

Pink Star diamond smashes the world record sale price at a whopping $71.2 million

pink-star-diamond-breaks-world-record-at-71-2-million image www.worldwidediamonds.info

The largest, most perfect pink diamond to have ever been offered at auction has sold for $71.2 million at a Sotheby’s event Tuesday in Hong Kong, setting a new world record for any diamond or jewel, according to the auction house.

Described as one of “the earth’s greatest natural treasures”, the oval-cut 59.6-carat “Pink Star” is the largest internally flawless pink diamond that the Gemological Institute of America (GIA) has ever had the privilege to grade.

Until now, the most expensive diamond ever sold at auction was the “Oppenheimer Blue,” which fetched 56.8 million Swiss francs (more than $57 million at the time) last May. The previous world auction record for a pink diamond was $46.2 million for the 24.78 carat “Graff Pink” in 2010.

First unveiled to the public in 2003, the Pink Star was called the “Steinmetz Pink,” but it was renamed after it was first sold for an undisclosed sum in 2007.

In 2013, the diamond broke a new world record price for a gemstone at auction by fetching $83.2 million in Geneva, way above the $60 million experts had predicted.

Not long after the sale, however, rumours began to spread that the consortium of buyers, led by diamond cutter Isaac Wolf, defaulted on the deal. In February 2014, Sotheby’s confirmed those unofficial reports and said the diamond was again part of its inventory, valued at approximately $72 million.

The Pink Star, originated from a 132.5-carat rough mined by De Beers in 1999 and it’s more than twice the size of the “Graff Pink.”

Massive Cullinan Dream blue diamond fetches over $25m at auction

Price fetched makes it the most expensive fancy intense blue diamond ever sold at auction.

The Cullinan Dream in the rough.

A 24.18-carat intense blue diamond known as The Cullinan Dream has just sold for $25.4 million at Christie’s Magnificent Jewels auction in New York, breaking all records and becoming the most expensive gem of its kind ever sold at auction.

The diamond, cut from a 122.52-carat rock found at Petra Diamond’s (LON:PDL) Cullinan mine in South Africa in 2014, is the largest of four blue diamonds made from the original.

The Cullinan Dream, a cut-cornered rectangular mixed-cut diamond, has been classified by the Gemological Institute of America as Type IIb. Those kinds of gems are very rare and account for less than one-half of 1% of all diamonds found in nature.

The Cullinan Dream is now a cut-cornered rectangular mixed-cut fancy intense blue diamond, weighing approximately 24.18 carats.

Type IIb gems contain a small amount of the element boron trapped in the crystal carbon structure during their formation that can give rise to a blue or grey coloration, Petra Diamonds said in a statement.

The mine is best known for the discovery of the Cullinan diamond, at 3,106 carats the largest rough diamond ever found. The gem was cut into two highly significant diamonds, which can be found in the British Crown Jewels.

It is flanked on either side by a tapered baguette-cut diamond and set in a platinum ring, inscribed “Cullinan Dream”.

Since acquiring a majority stake in the mine in 2008, Petra Diamonds has found some high-profile blue diamonds, including “The Blue Moon of Josephine,” which sold in November for $48.5 million and “The Star of Josephine” — a 7.03 carat polished stone that sold in 2009 for $9.49 million, representing what at the time was a world record price per carat of $1.35 million.
