Necklace With Two Golconda Diamonds Could Fetch $10 Million

The Eye of Golconda

“The Eye of Golconda,” A necklace featuring two statement Golconda diamonds will be the top lot at Christie’s Hong Kong Magnificent Jewels auction on May 27.

The diamond pendant and emerald necklace has a 40.05-carat pear-shaped diamond and a 6.76-carat cushion-shaped diamond, both graded by the Gemological Institute of America as D color with internally flawless clarity. The former, the necklace’s pendant centerpiece, is the largest Golconda diamond ever available for auction in Asia. The necklace has a pre-auction estimate of $8.5 - $10 million.

Both diamonds are graded as Type IIa, which are a trait of diamonds from mines in the historic Golconda area of India. Type IIa diamonds represent less than 2 percent of the world’s production of gem-quality diamonds and are considered the purest form of diamonds and show exceptional optical transparency.

Golconda diamonds are often described as “Diamonds of First Water,” according to the auction house, because they are characterized by “an almost indefinable water-clear appearance that attest to their diaphanous quality and a degree of transparency rarely seen in stones from other localities.” Some of the most famous diamonds in the world are believed to have come from mines in the Golconda region including the Koh-i-noor, Darya-e Nur, the Nur-Ul-Ain, and The Hope Diamond.

The auction will have more than 300 lots with a combined estimate of more than $100 million. It includes several rare colored diamonds, colorless diamonds, rare Jadeite jewels, Burmese rubies and sapphires, and Colombian emeralds. Exclusive vintage jewelry pieces from Bulgari, Harry Winston and Van Cleef & Arpels complete the sale.

Other highlights of the auction include:

* A 9.38-carat pear-shaped fancy intense pink diamond on a ring with an estimate of $5.8 - $8.3 million.

* Two unmounted 26.08 and 26.20 carats D color flawless, Type IIa brilliant-cut diamonds. Each diamond has an estimate of $4 - $6.5 million. They have been awarded "Excellent" for polish, symmetry and cut grade, meaning that they exhibit perfectly aligned facets with an accuracy of up to 1/200th of an inch, while each of the facets is worked to the greatest possible smoothness.

* It wouldn’t be a Hong Kong jewelry auction without statement jadeite pieces. The top lot in this category is a jadeite bangle with an estimate of $3.8 - $6.5 million. Christie’s says it has the “perfect balance of the ideal color, texture and translucency” displaying a “vivid emerald green color with a saturation and tone that are neither too dark nor too light.”

* A Burmese “pigeon’s blood red” ruby and diamond jewelry suite by James W. Currens for Faidee has an estimate of $4 - $6.25 million.

The auction will be held at the Hong Kong Convention and Exhibition Centre with public viewings beginning May 22.

Graff Vivid Yellow Diamond Made Two Appearances Before Selling for a Record $16.3 Million

It was a long journey for the "Graff Vivid Yellow" diamond but it did eventually find an owner during Sotheby's Geneva Magnificent Jewels and Noble Jewels auction Tuesday.

It was the top lot of an auction packed with exceptional jewels that had to make two appearances before being sold for more than $16.3 million (hammer price, commission and fees), a world auction record for a yellow diamond and for a Graff diamond, according to the auction house.

David Bennett, chairman of Sotheby's Jewellery Division in Europe and the Middle East, stunned the standing room crowd during the evening session of the auction at the Hôtel Beau-Rivage when he pulled the 100-carat diamond with an 11.8 million Swiss franc bid on the block. However, about 15 minutes later the stone suddenly reappeared and bidding reopened. The bidding began at 12.6 million Swiss francs, which was quickly raised to 12.8 million. Bennett then struck the gavel saying it was a good bid. The estimate for the diamond was $15 - $25 million.

After the auction, Bennett explained that the buyer, a women in the front of the room who did not want her identity revealed, asked to have the item returned. He added that something like this does happen occasionally but almost never with such a high-profile piece.

"The eventual buyer of the yellow diamond who was in the room got confused, I think, with her calculations of francs and dollars and came back a few minutes later and said could you re-offer it because we still wanted to buy. It was quite a nice thing to happen," a "happy and relieved," Bennett said.

He further explained that he knew who would be bidding on the piece as there are only a few people in the world capable of paying $15 million for a diamond. He added that the buyer appeared even happier than he was.

The drama overshadowed a three-session auction where at least seven records were set, according to the auction house. Highlights included:

* The highest total ever achieved for an auction of  jewelry from various owners at more than $141.4 million.

* A 70.33-carat D-color, flawless cushion brilliant-cut, type IIa diamond sold for more than $14.2 million, followed by a round of applause.

A 12.07-carat marquise-shaped fancy pink diamond ring sold for more than $7.2 million, setting a world auction record for a price per carat for a pink diamond at $601,228 US per carat.

* One of the largest round diamonds in the world at 103.46 carats set on a ring by Graff sold for more than $4.8 million.

* A 25.32-carat brilliant-cut, D color, IF diamond sold for more than $6.2 million and $246,710 per carat, setting a world auction record price per carat for a round colorless diamond.

* The last lot of the evening, a ring set with two fancy blue pear-shaped diamonds, one fancy vivid weighing 3.08 carats the a fancy intense blue of 2.83 carats, sold for nearly $6.5 million.

* Jewels from the collection of Flora Sassoon totaled more than $3.3 million, led by a diamond necklace that sold for more than $1.2 million, well above its $700,000 high estimate.

World’s Biggest Diamond Sale Becomes World’s Biggest Diamond Default

Sotheby’s said Thursday that the high-bidder of the 59.6-carat “Pink Star” diamond that sold for a world record price of $83.2 million has defaulted.

Diamond cutter Isaac Wolf, who said he was representing unnamed investors, outbid three rivals for the gem at Sotheby’s Geneva Magnificent Jewels Sale held in November. He renamed it the “Pink Dream.”

Wolf was unable to pay for the flawless fancy vivid pink diamond, according to the auction house’s annual report. It is now part of Sotheby’s inventory valued at approximately $72 million

According to a report on CNBC, the auction house had to buy back the diamond for $60 million because it had guaranteed that price to the original seller of the gem, whose identity is unknown.

In a conference call with investors Thursday, Patrick McClymont, Sotheby’s CEO, said the auction house is still talking with Wolf about the future of the diamond.

“We are currently in discussions with the buyer while also considering other alternatives,” he said. “In the meantime, we are comfortable with our valuation and see real value in owning the diamond at this price.”

Wolf in a YouTube video explaining the purchase said he was representing a group of investors and considered the diamond to be worth about $150 million, based on current prices for pink diamonds of similar quality.

“It’s not that I’m buying this with the money that I have in my piggy bank,” Wolf said. “It’s basically a group of investors—financial people—that are backing me on this and they are doing this as an investment, and hopefully to make a big profit.”



The diamond is graded as Type IIa, which is rare for any pink diamond, much less one of this size and color. It is twice the size of any vivid pink diamond ever brought to auction and the largest known diamond rated vivid pink. David Bennett, chairman of Sotheby’s Jewellery Division in Europe and the Middle East and chairman of Sotheby’s Switzerland, said the diamond is one of the most important gems he has seen in his 35-year career.

“It is difficult to exaggerate the rarity of vivid pink diamonds weighing only five carats,” he said prior to the auction. “So this 59.60 carat stone is simply off any scale, and passes, I believe, into the ranks of the earth’s greatest natural treasures.”

The oval-cut gem was the highlight of the November auction in Geneva. It was estimated to fetch more than $60 million. The bidding opened at $48 million and lasted for about five-minutes before Wolf made the winning bid.

The diamond was originally mined in South Africa in 1999 as a 132.5-carat rough by De Beers. It was cut by the Steinmetz Diamond Company over a two-year period and was formerly known as Steinmetz Pink. In 2003, it was shown publicly in Monaco and was displayed at the Smithsonian Institute as part of its “Splendor of Diamonds” exhibit, according to Wikipedia. The Pink Star was sold privately in 2007.

52-Carat Golconda Diamond Sells For $10.9 Million

A rare 52.58-carat D-color internally flawless Golconda diamond fetched $10.9 million at Wednesday’s Christie’s New York Magnificent Jewels auction.

Diamonds from the ancient Golconda mines in India are revered for their type, color and degree of transparency that is rarely duplicated.

In addition, a collection of Leviev diamond jewelry under the heading “Property of an Elegant Lady” was sold for $10.2 million, led by a 26.72-carat D color internally flawless diamond that sold for $4.3 million.

The 495-lot auction, the final jewelry sale of the year for the auction house, realized more than $65.7 million, with 86 percent sold by lot and 92 percent by value. The results of the December Sale in combination with the results achieved by the New York jewelry auctions in April and October, brings the 2013 New York Magnificent Jewels total to nearly $193.9 million.

Christie’s To Offer 52-Carat Golconda Diamond

Christie’s New York will be offering a 52.58-carat D-color internally flawless diamond from the fabled Golconda mine, revered for producing diamonds of a type, color, and degree of transparency that is rarely duplicated. It has a high estimate of $12.5 million.

The octagonal diamond with “superior polish” is the top attraction among 500 lots being offered at the December 10 Magnificent Jewels sale at Christie’s Rockefeller Center headquarters.

The auction is expected to achieve in excess of $45 million and will include jewels by several private collections, including four pieces of diamond jewelry created by the Leviev diamond company. The top item among the four pieces is a cushion-cut D-color internally flawless diamond ring of 26.72 carats mounted in platinum, flanked on either side by a shield-shaped diamond. It has a high estimate of $6 million.

In addition, there’s a diamond pendant necklace with a suspended 22.12-carat pear-shaped d-color, VVS1 diamond. The necklace has a high estimate of $3.5 million.

The Pink Star Diamond Fetches World Auction Record Of $83 Million

The 59.6-carat Pink Star diamond lived up to its hype by selling for a world record price of approximately $83.4 million at Sotheby’s Geneva Magnificent Jewels sale Wednesday.

When introducing the internally flawless fancy pink vivid diamond, David Bennett, chairman of Sotheby’s Jewellery Division in Europe and the Middle East, called it “one of the most remarkable gems to ever appear at auction.”

Bidding opened at 48 million Swiss francs and gradually climbed to 64 million Swiss francs. After a pause it quickly climbed to 67 million francs ($73.2 million), shattering its $60 million high estimate. Nervous laughter could be heard on Sotheby’s live feed as the bidding slowly pushed up to the winning bid 68 million Swiss francs. Commission fees pushed the final total to more than 76.3 million Swiss francs ($83.4 million).

The diamond is graded as Type IIa, which is rare for any pink diamond, much less one 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 of $2,155,332 is set by a 5-carat diamond, sold in Hong Kong in January 2009. The current record price for any colored diamond sold at auction is $2,398,151 per carat, for “the Orange,” a 14.82-carat fancy vivid orange diamond that sold a day earlier at Christie’s Geneva Magnificent Jewels auction. The per carat price for the The Pink Star has yet to be released and will be updated.

Cut by Steinmetz Diamonds over a period of nearly two years 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.

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.

The auction at Christie’s Rockefeller Center headquarters took in more than $46.6 million with 75 percent of the items sold by lot and 85 percent sold by value.

Kim Kardashian’s 20-Carat Engagement Ring Fetches $749,000 At Auction

Kris Humphries reportedly said he just wanted to move on so he can’t be too disappointed for the price his 20.5-carat diamond engagement ring to Kim Kardashian achieved at auction Tuesday.

The NBA basketball player, who paid a reported $2 million for the diamond and platinum ring for the reality TV star in 2011, saw the ring sell for $749,000 during Christie’s Magnificent Jewels auction. While the ring did not sell for its original price it did easily exceed the high auction estimate of $500,000.

Listed simply as an “Impressive Diamond Ring,” the ring designed by Lorraine Schwartz is set with a 16.21-carat rectangular-cut diamond with I color, VS1 clarity. The diamond is flanked on either side with a trapeze-cut diamond, each weighing approximately 1.80 carats. 

The celebrity couple separated after 72 days of marriage in 2011. The divorce became final in 2012.

Although reports started circulating as to the owner of the ring, the provenance wasn’t confirmed until an unidentified person representing Humphries told E! News that it was indeed being sold by him. 

“He has long-since moved on and is very much looking forward to a successful auction at Christie's on Tuesday, and of course to returning to the court this upcoming NBA season as a Boston Celtic,” the representative said in a statement to the entertainment news network.

Rahul Kadakia, head of Jewelry for Christie’s Americas and Switzerland, who led the auction, announced that a portion of proceeds will benefit a charity. 

Bidding began at $200,000 and quickly rose to $480,000. After a pause it went to $520,000. It then slowly climbed to reach a final bid of $620,000. Commission and fees bought the price of the ring to $749,000.

It was the last item of the morning session of the auction. It is scheduled to resume at 2:30 p.m.

Largest Known Orange Diamond May Fetch $20 Million at Auction

The largest fancy vivid orange diamond ever to appear at auction will be the top lot in Christie’s Magnificent Jewels sale to be held in Geneva on November 12. Weighing approximately 14.82 carats, this diamond, being called “The Orange,” is expected to fetch between $17 million and $20 million.

Pure orange diamonds, also named ‘Fire diamonds’ by gemologist Edwin Streeter in his book The Great Diamonds of the World (1882), are exceptionally rare in nature. 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 less than 6 carats. “The Orange” is more than double that size.

At 5.54 carats, the Pumpkin diamond was largely considered to be the largest known fancy vivid orange diamond. It was purchased by Ronald Winston for $1.3 million and made into a ring by Winston and Phillip Bloch. Best Actress winner Halle Berry wore the ring to the 2002 Academy Awards.

A 4.19 carat fancy vivid orange diamond sold for a record price of $2.95 million in October 2011 at a Sotheby’s auction.

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.”

Sotheby’s To Sell ‘Most Valuable Diamond Ever to be Offered at Auction’

The 59.60 carat Pink Star may fetch $60 million.

Sotheby’s Geneva will offer a 59.60-carat internally flawless vivid pink diamond at its Magnificent Jewels sale on November 13. Known as The Pink Star, the auction house says it is the most valuable diamond ever to be offered at auction. It is estimated to sell for more than $60 million. For those counting that’s more than $1 million per carat.

The oval cut gem is the largest internally flawless fancy vivid pink diamond that the Gemological Institute of America has ever graded, the auction house said.

David Bennett, chairman of Sotheby’s Jewellery Division in Europe and the Middle East and chairman of Sotheby’s Switzerland, said the diamond is one of the most important gems he has ever seen in his 35-year career.
 

“Its exceptional richness of color … combined with its extraordinary size, are characteristics that surpass those of any known pink diamond in state, royal, or private collections,” he said. “It is difficult to exaggerate the rarity of vivid pink diamonds weighing only five carats, so this 59.60 carat stone is simply off any scale, and passes, I believe, into the ranks of the earth’s greatest natural treasures.”

The diamond is also graded as Type IIa, rare for a pink diamond of this size and color. Cut over a period of two years, The Pink Star is still 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.

Owner of 75-Carat Briolette Diamond Names it 'Star of China'

Tiffany Chen poses by a picture of the 75-carat Star of China diamond while wearing the gem after purchasing it for $11.15 million.

The new owner of what Christie’s auction house has called the largest and most perfect briolette diamond ever sold at auction has identified herself and picked a name for the 75.36-carat gem.

Tiffany Chen, vice chairman of China Star Entertainment Ltd., has revealed herself to be the owner of the briolette diamond. She named the diamond after her company, “The Star of China.”

Chen purchased the diamond May 28 at Christie’s Hong Kong Magnificent Jewels sale for $11.15 million, $148,000 per carat, a world record for a briolette diamond sold at auction.

The briolette has been graded by the Gemological Institute of America to be of D color and type IIa, indicating its internally flawless clarity, excellent polish, highest level of chemical purity and exceptional optical transparency. Less than one carat in every 100,000 carats of diamonds is found to be found in this perfect condition.

The diamond is part of a pendant necklace that includes a marquise-cut purplish pink diamond suspended above the briolette.

74-Carat Diamond Fetches A Record $14.1 Million

A 74.79-carat, pear-shaped diamond sold for more than $14.1 million at Sotheby’s New York Magnificent Jewels sale Wednesday, setting a new auction record for any white diamond sold in the Americas and surpassing its $12 million high estimate.

The unnamed gem is one of very few pear-shaped diamonds of D color over 50 carats to be auctioned in recent decades, Sotheby’s said.

“The truly exceptional 74.79 carat stone was a thrill to auction, and exemplifies the strength of the market for white diamonds over the last decade,” said Lisa Hubbard, chairman, North & South America, Sotheby’s International Jewelry Division. “It was acquired by the present owner in 2001 for $4.3 million, and today sold for a record $14.2 million.”

The Magnificent Jewels sale brought in nearly $53.5 million, marking a new record sum for a spring auction of jewelry at Sotheby’s New York, with more than 82.4 percent sold by lot.

A group of six jewels from the family of financier and railroad magnate Jay Gould sold for a combined $7.9 million, more than double its high estimate of $3 million. The group was led by an emerald and diamond brooch centered by a 22.48-carat Colombian emerald that sold for $2.9 million– nearly five times its high estimate of $600,000.

Cartier’s ‘Tutti-Frutti’ bracelet (circa 1930), made of platinum, carved rubies and emeralds, diamonds and pearls, which closed the sale, sold for $1.4 million, nearly three times its high estimate of $500,000.

The Princie Diamond Sells for a Record Breaking $39.3 Million

The 34..65-carat Princie Diamond

Update: A 34.65-carat fancy intense pink cushion-cut diamond sold for more than $39.3 million at Christie’s New York Spring Magnificent Jewels auction Tuesday.The sale price represents a new record for any jewel sold at Christie’s, surpassing the previous house record of $24.3 million set in December 2008 with the sale of the Wittelsbach Diamond.

Known as the Princie Diamond, its origins can be traced back to the ancient diamond mines of Golconda in South Central India. It was first recorded among the holdings of the Royal family of Hyderabad, rulers of one of the wealthiest provinces of the Mughal Empire.

The sale price, which comes out to more than $1.1 million per carat, also set a record for being the most valuable diamond to ever come out of the famed mine, according to the auction house. It was purchased by an anonymous collector bidding by phone.

“A major event took place in the global auction industry with the record breaking sale of The Princie Diamond at Christie’s New York,” said Rahul Kadakia, Head of Jewelry, Christie’s Americas and Switzerland.

The Type IIa diamond, considered the most chemically pure and often having exceptional optical transparency, was first offered at auction in 1960 as “Property of a Gentleman,” who was later revealed to be the Nizam of Hyderabad himself. The diamond was purchased by the London branch of Van Cleef & Arpels for £46,000. The diamond’s unique name was bestowed at a party at the firm’s Paris store, where it was christened the “Princie” in honor of the 14-year-old Prince of Baroda, who attended the party with his mother Maharani Sita. 

 The total sale of over 290 jewels realized a combined total of more than $81.35 million, "marking the highest various owner jewelry sale total in the United States," according to the auction house.

"Aside from Christie’s sale of the legendary Collection of Elizabeth Taylor, this was the most successful jewelry auction ever held in the United States,” Kadakia said.

Other highlights of the sale, which marked the first jewelry sale of the spring season for Christie’s, included:

* A 30.32-carat rectangular-cut diamond ring (pictured above) that sold for more than $4.4 million, well above its high estimate of $4 million. The diamond set on a platinum ring is flanked on either side by a tapered baguette-cut diamond.
