‘Oppenheimer Blue,’ ‘Unique Pink’ Set For Auction In Geneva

The Oppenheimer Blue could fetch $45 million

Two rare statement colored diamonds will highlight the upcoming Sotheby’s and Christie’s jewelry auctions in Geneva this week. 

The item getting all the press (and for good reason) is the 14.62-carat “Oppenheimer Blue,” which is the highlight of Christie’s Geneva Magnificent Jewels sale at the Four Seasons Hotel des Bergues on Wednesday. It is “the largest and finest fancy vivid blue diamond ever offered at auction,” according to the auction house. 

If it goes beyond its high estimate of $45 million, it could outpace the “Blue Moon of Josephine,” a 12.03-carat cushion-shaped fancy internally flawless vivid blue diamond that set a world auction record of $48.4 million in November, 2015.

The diamond was previously owned by Sir Philip Oppenheimer, a member of the family that once controlled the De Beers Mining Company. He is credited with serving for 45 years as chairman of the Central Selling Organization, the sales cartel set up by De Beers to keep strict control over the diamond supply worldwide. He died in 1995 at the age of 83.

While the Oppenheimer Blue is the star of the Geneva jewelry auctions, there will be several other statement pieces on the auction block. In particular, the “Unique Pink,” (pictured above) which goes on sale at Sotheby’s Magnificent Jewels and Noble Jewels sale at the Hôtel Beau-Rivage. The pear shaped 15.38-carat fancy vivid pink diamond has a high estimate of $38 million. It is the largest fancy vivid pink pear shaped diamond ever offered at auction, according to the auction house. “In my experience, such outstanding vivid Pink color in a stone over 15 carats is truly unique,” said David Bennett, worldwide chairman of Sotheby’s International Jewellery Division.

At the same auction, a pear shaped 7.32-carat fancy vivid blue diamond ring will be offered with a high estimate of $25 million (pictured above).

Meanwhile, Christie’s will be offering earrings with matching fancy vivid orange-yellow diamonds of 12.20 and 11.96 carats (above). One diamond with this color is extremely rare, let alone two matching diamonds. The high estimate for the pair, named “The Oriental Sunrise,” is $12.2 million. The origin of the diamonds is unknown or unavailable.

Harry Winston purchased the sparkling gem for nearly $23.8 million at Christie’s Geneva Magnificent Jewels sale. At nearly $1,800 per carat, the price per carat paid for the 13.22-carat stone represents a world record for a blue diamond.

It is the second major diamond purchase by Harry Winston since it was acquired by the Swatch Group, one of the world’s largest watch and jewelry conglomerates. Last year, Harry Winston purchased a 101.73-carat colorless diamond for a world record $26.7 million ($254,400 per carat), at Christie’s Geneva jewelry auction.

World’s Largest Orange Diamond Sells For A World Record $35.5 Million

A 14.82-carat fancy vivid orange diamond set two world records as it sold for more than $35.5 million at Christie’s Geneva Magnificent Jewels sale held Tuesday.

Simply called “The Orange,” the gem set a world record for a fancy vivid orange diamond. And at $2,398,151 per carat, it also set a world record price per carat for any colored diamond sold at auction. It shattered its high estimate of $21 million.

“Time and again, a stone will appear on the market that is truly a miracle of nature,” said François Curiel, International head of Christie's Jewellery Department. “The 14.82-carat orange diamond is one such a stone, a rare gem, which will perhaps only be seen once in a lifetime. In the sale on Tuesday, it soared far above all previous records for any orange diamond ever sold at auction, placing The Orange among the greatest pinks and blues, which are traditionally the most appreciated colored diamonds.”

There was little question that the diamond was going to fetch a record price. It is believed to be easily the world’s largest orange diamond. It is approximately three times larger than the two other known large orange diamonds: The 5.54-carat “Pumpkin Diamond,” which was sold privately, and a 4.19 carat fancy vivid orange diamond sold at auction for a record price of $2.95 million in October 2011.

It was the last of the 286 lots that were up for sale at the auction held at the Four Seasons Hotel des Bergues. 

The bidding opened at 10 million Swiss francs and quickly reached $20 million francs before the bidding slowed and the increments of bids switched from 1 million francs to a half-million. It appeared on the Christie’s live Internet feed that several bidders were in the room competing with those on the phones. Applause followed the winning bid of 29 million francs ($31.6 million). The final total of $35,531,974 million includes fees and commissions.

Pure orange diamonds are exceptionally rare, the auction house said. It is more common to find orange diamonds with secondary colors. The orange color is the result of the presence of nitrogen during the diamond’s creation.

The Gemological Institute of America, which graded the diamond and issued its report, recently said: “Strongly colored diamonds in the orange hue range rarely exceed three or four carats in size when polished. (This diamond) is almost four times larger than that size range. In GIA’s colored diamond grading system, as the color appearance of strongly colored diamonds transitions from orangy yellow to orange the occurrence becomes progressively more rare—that is—the less yellow present the more rarely they occur.”

In the GIA report, the diamond was graded as VS1 clarity, and classified as a Type IA.

Big Pink and Orange Diamonds to Lead Geneva Auctions

The 59.6 carat "Pink Star."

If one would compare major jewelry auctions to prizefights (like I’m doing), then the large, statement diamonds would be the heavyweight contenders. The top prizes in the heavyweight division this year are extremely rare fancy colored diamonds that will be put up for auction in Geneva this week by Sotheby’s and Christie’s.

Sotheby’s on Wednesday will be offering what it calls “the most valuable diamond ever to come to auction” as part of its Magnificent Jewels sale. The Pink Star is a 59.6 carat internally flawless fancy pink vivid diamond and has a pre-sale estimate in excess of $60 million.

The diamond is graded as Type IIa, which rare for a pink diamond of this size and color. Cut over a period of two years, The Pink Star is more than twice the size of the Graff Pink—a 24.78-carat fancy intense pink diamond that established a world auction record for a diamond and any gemstone or jewel at $46.2 million, at Sotheby’s Geneva in 2010. The current record price per carat for a fancy vivid pink diamond ($2,155,332) set by a 5-carat diamond, sold in Hong Kong in January 2009.

Cut by Steinmetz Diamonds from a 132.5-carat rough, the diamond was first unveiled to the public in May 2003 as the “Steinmetz Pink.” The stone was first sold privately in 2007 and renamed The Pink Star.

In total, the Sotheby’s Magnificent Jewels sale will comprise over 370 lots, including iconic jewels, such as the “Walska Briolette Diamond” brooch with an estimate in excess of $8 million. The total sale has a pre-sale estimate of $123 million to $167 million.

The 14,82 carat "Orange"

Meanwhile, on Tuesday, not to be outdone, Christie’s will sell the largest fancy vivid orange diamond ever to appear at auction at its Magnificent Jewels sale. Weighing approximately 14.82 carats, this diamond, called simply “The Orange,” is expected to fetch between $17 million and $21 million.

Pure orange diamonds are exceptionally rare, the auction house said. It is more common to find orange diamonds with secondary colors. The orange color is the result of the presence of nitrogen during the diamond’s creation. Among the very few fancy vivid orange diamonds that were ever sold at auction, the largest was the “Pumpkin Diamond” 5.54 carats. The Orange is more than double that size. A 4.19 carat fancy vivid orange diamond sold at auction for a record price of $2.95 million in October 2011.

Other items being presented at Christie’s Magnificent Jewels auction include three jewels from the world famous collection of Bolivian tycoon Simón Itturi Patiño, with the highlight being an emerald and diamond necklace by Cartier, 1937. The ‘Property of Hélène Rochas’ will include 18 lots, with a rare diamond and colored diamond ‘Tiger’ shoulder brooch, by Boivin. The Art Deco period will be represented by HRH Princess Faiza of Egypt emerald drop and diamond necklace by Van Cleef & Arpels, 1929, and an “Orientalist” emerald and diamond sautoir by Cartier, 1926.

Christie's Geneva to Sell 101-Carat Flawless Diamond

Christie’s Geneva is offering what it says is the world’s largest flawless diamond to ever be offered at auction. The auction house calls the 101.73-carat, pear-shaped D color, type IIA flawless gem “absolute perfection.” It will be the highlight of the May 15 Magnificent Jewels auction at the Four Seasons Hotel des Bergues. The estimate is available upon request.

“A perfect diamond is the result of the skill and vision of a master cutter who is able to uncover beauty from a rough gem,” said Rahul Kadakia, head of Jewellery, Christie’s Switzerland and Americas. “This diamond is in its scale, quality and rarity one of the most beautiful ‘white’ diamonds Christie’s has ever had the honor of offering for sale.”

The diamond meets every criteria of perfection, according to the auction house. The Gemological Institute of America graded it with the best color, D, and the best clarity. In addition, fewer than 2 percent of the world’s diamond meets the type IIA criteria for transparency and brilliance.

The diamond was carved from a 236-carat rough diamond that was found at the Jwaneng Mine in Botswana, according to the auction house. It took 21 months to polish.

Out of a total annual worldwide diamond production in excess of 100 million carats, the Gemological Institute of America estimates there are no more than 600 diamond crystals that finish as polished stones between one and two carats and that are D color, flawless clarity, the auction house says. Above ten carats this figure decreases dramatically. For a diamond of more than 100 carats …

Possibly the world's first chronograph. CHRISTIE'S IMAGES LTD. 2012

A timepiece of historical significance that was part of the auction was what may have been the first chronograph. It sold for $245,274. The “probably unique” and historically important inking chronograph with cylinder escapement, housed in mahogany box is signed Rieussec Horologer du Roi, Chronographe, Brevet d'Invention, circa 1821/22.

Nicolas Mathieu Rieussec is credited with inventing the chronograph on September 1, 1821.

The timepiece has a mechanical cylinder movement, plain three-arm balance, two revolving silvered dials on the front plate—the upper one for minutes, the lower one for seconds—both with fixed blued steel inking hand, brass button on the left side of the fausse-plaque activates the inking hand, brass button on the right starts and stops the movement, front plate signed. It measures 143 mm. long & 114 mm. wide not including the box.

This lot includes a note from Christie’s, which reads as follows:

It is very interesting to note that this historically important inking chronograph by Rieussec is not numbered, but instead inscribed "Chronographe, Brevet d'Invention". One may speculate for the reasons why Rieussec didn't number this superb piece, but one very logical explanation may be that this example here is the very one he used to obtain his patent.

Another interesting item that received a great deal of interest was a set of two Vaucher, Fleurier 18K gold and enamel identical numbered, mirror-image pair of openface center seconds duplex watches with matching gold and enamel keys and fitted box, made for the Chinese market.

76-Carat Archduke Joseph Diamond Expected to Fetch $15 Million

-->

The Archduke Joseph Diamond ©Tony Falcone

It has royal origins and was owned by royalty and now the legendary Archduke Joseph Diamond will be offered at Christie’s auction in Geneva on November 13. The auction house says it is one of the rarest and most famous diamonds in the world that combines an impressive size of 76.02 carats, perfect color, and internally flawless clarity.

Christie’s says the estimate is available on request but it is expected to achieve $15 million in the upcoming auction.

Its origin is traced to the ancient Golconda mines in Central India, the source of the world’s most coveted historical diamonds, including the Koh-i-noor, in the Royal Collection at the Tower of London; the Regent, considered the finest diamond in the French Crown Jewels, at the Musée du Louvre in Paris; and the Hope, gifted by Harry Winston to the Smithsonian Institution in Washington D.C.

This same diamond “created a sensation when Christie’s Geneva offered it for sale the first time in November 1993 where it realized CHF 9.7 million (US$ 6.5 million)—the equivalent of $10.5 million today,” said François Curiel, International Head of Christie’s Jewellery Department. “The magic of auction sometimes brings back great gems to our salerooms more than once.”

Although it is not known exactly when the diamond entered the House of Habsburg, it has been officially recorded as the property of the Archduke Joseph August of Austria, Palatine of Hungary (1872-1962), and was subsequently named after him.
