Sotheby’s Magnificent Jewels and Noble Jewels sale is jam-packed with incredible jewel after incredible jewel. Leading the 500-lot sale is the exceedingly rare and outrageously beautiful Blue Moon diamond. This rare wonder, graded Fancy Vivid Blue and Internally Flawless, was unearthed at the Premier Mine at Cullinan – owned by Petra Diamonds – in South Africa, the only known mine today for producing blue diamonds with some regularity. In fact, out of the eighteen million tons mined and five million carats recovered from the mine, only five world-class blue diamonds have emerged from Cullinan, or less than 0.1 percent of the mine’s annual yield.

The 29.62-carat rough found in January 2014 was expertly cut by Cora International, one of the world’s leading firms specializing in cutting large important diamonds. The resulting stone, a cushion-cut 12.03-carat diamond of perfect proportions, is a masterpiece of mother nature enhanced by the hands of man. The Blue Moon is expected to fetch between $35.5 and $56 million.

Opposite in color but no less exceptional, the Queen Maria-José ruby ring is a fiery wonder of impeccable provenance. Formerly part of the personal collection of the last Queen of Italy, Maria-José, the historic ruby was a gift from the Italian bibliophile Tammaro de Marinis on the occasion of Maria-José’s wedding to Crown Prince Umberto in 1930. The Burmese ruby weighs 8.48 carats and is noted to have the coveted ‘pigeon’s blood’ red hue. The rare ruby is estimated at $6 to 9 million.

Sotheby’s has a knack for record-breaking rubies in the past year. In November 2014, the auction house sold the ‘Graff Ruby’ for $8.6 million, a new world record for a ruby at the time. Then, in May of this year, Sotheby’s Geneva bested the world record for a ruby again with the sale of the ‘Sunrise Ruby’, an exquisite 25.59-carat Burmese ruby that sold for $30.3 million – more than three times the previous record.

Another important stone in the sale is a pear-shaped 8.24-carat Fancy Vivid Purple-Pink diamond, estimated at $12.6 to 16.6 million. Last year, in October, Sotheby’s Hong Kong offered a 8.41 carat Fancy Vivid Purple-Pink diamond, which sold for $17,778,247, a world auction record price for a fancy vivid pink diamond.

While the sale boasts a bevy of remarkably rare gems, it also offers a plentitude of highly collectible jewels, including hree magnificent tiaras. Cartier is well represented in the sale, with terrific examples illustrating the breadth and talent of the maison throughout the 20th century: from a delicate 1920s natural pearl, emerald and diamond jabot pin, its design inspired by a traditional Indian sarpech, a turban ornament, to a more modern emerald, ruby, mother-of-pearl and diamond ‘New Khandy’ parrot brooch and everything in between.


A number of Cartier pieces from the 1940s and 1950s display the creative spirit during and after World War II. A citrine suite in particular is a stunning illustration of beautiful jewelry made during the wartime rationing, during which the more precious materials were strictly limited.

Topaz bangle, Suzanne Belperron, circa 1935 - Estimate $40,581 - 61,392

The sale also includes beautiful pieces by renown jewelers such as René Lalique, Suzanne Belperron, René Boivin, and Jacques Lacloche as well as notable jewels from the world’s most prestigious jewelry houses, including Bulgari, Harry Winston, Tiffany & Co. and Van Cleef & Arpels. For connoisseurs looking to add contemporary pieces to their collections, the sale offers stunning jewels by JAR, Alexandre Reza and Hemmerle.


Christie’s Incredibly Magnificent Jewels Of 2014

Christie’s has been able to give us quite a year for fancy color diamond news. In May 2014, it sold the largest Flawless Blue diamond, the 13.22 carat diamond now renamed the Winston Blue. They also broke the jewelry world auction record when they made over $150 million in sales, they broke the world record price for a red diamond in HK in November, and now last but not least they are giving us the last Magnificent Jewels show in NY. Will they break any more records? Nothing in the auction lists stands out as phenomenal, but as we all know, anything is possible!

We have quite a few items to focus on, including two stones that are from past Argyle tender events – one recent (from 2013), and one from the not too far past, 2003.

This time I will also be presenting the stones in the order of estimation of price by Christie’s.

The star of the evening for us is a rare 21.30 carat Fancy Light Pink diamond of exceptional quality and color as it is a Golconda Type IIa diamond with VS1 clarity. It is estimated to sell at a price between $4 million and $6 million. Since the price spread is quite significant, I am sure we will see quite the bidding war here.

21.30 carat Fancy Light Pink Golconda diamond

My next choice is pure art in jewelry form. Various color diamonds are combined to create a masterpiece, while allowing quite the display of value creation. This collection is valued at between $3.5 million – $5 million.

A total of over 100 carats in these earrings, this pair features a 52.88 carats VS1 diamond and a 51.46 carats VS2 diamond, both pear shaped and both Fancy Light Yellow. Large enough to get attention yet a subtle color, they are valued between $2.5 million and $3.5 million.

52.88 carat Fancy Light Yellow VS1 diamond and 51.46 carat Fancy Light Yellow.VS2 diamond earrings

This item may or may not break a record, but will surely grab attention. This 1.42 carat Fancy Red is a previous Argyle tender stone. Lot #11 from the 2013 tender, it used to be a 1.66 carat Fancy Deep Pink, but it was re-polished to realize the potential of the stone. This practice is common when there is recognizable potential there, but only a handful of experts globally can do it properly. This stone is valued between $1.5 million and $2.5 million. In order to break the world record, this stone would have to sell for $3.47 million total or more. We shall see!

1.42 carat Fancy Red diamond (Argyle tender stone Lot #11 from 2013)

Up to now I have concentrated on both Fancy Intense and Fancy Vivid Blue diamonds. It seems that I may need to add Fancy Blue to my research as we see great importance given to this depth of color as it is also quite rare. This stone, a rarely seen weight of 5.70 carats and VS1 quality, is valued between $1.5 million and $2.5 million.

5.70 carat Fancy Blue VS1 diamond

I like this diamond. Other than the certificate, where else do we see a brown tint here? A great looking Fancy Brownish Pink diamond weighing in at 14.28 carats, this diamond is special also due to its IF clarity. A real value can be shared here. Estimated between $1 million and $2 million, it may actually surprise us.

Every auction must have some special Fancy Intense or Fancy Vivid Yellow diamond, and this one is no exception. Coming in at 25.16 carat Fancy Intense Yellow with a VS1 clarity, this one is expected to be sold for anywhere between $500k and $700k.

Lots 198, 199, 200, and 201 had to be displayed as a group – it was just stunning the way they are displayed together. Lot 198 is a 0.73 carats Fancy Blue diamond valued at $90k – $120k. Lot 199 is a 0.51 carat Fancy Vivid Pink with 2 flattering Fancy Blue diamonds coming in at 0.28 and 0.27 carats on the shoulders and valued at a total of $140k – $200k. Lot 200 is a 4.06 carat Fancy Grey Green valued at $100k – $150k. Finally, Lot 201 is a special one – a 0.76 carat Fancy Deep Pink, Argyle tender stone #18 from the 2003 tender and valued at $100k – $150k.

New York–Christie’s New York is poised to sell the largest fancy intense pink Golconda diamond ever offered at auction when the “Princie Diamond” goes up for bid on April 16.

The Princie is a 34.65-carat fancy intense pink cushion-cut diamond whose origin can be traced to the ancient Golconda mines in south central India. The stone was first recorded as belonging to the royal family of Hyderabad, who ruled one of the wealthiest provinces of the Mughal Empire.

First offered at auction in 1960 by the Nizam of Hyderabad, the London branch of Van Cleef & Arpels purchased the Princie Diamond for £46,000 (approximately $69,588 in today’s currency). The diamond got its name at a party at Van Cleef’s Paris store, where it was christened in honor of the 14-year-old Prince of Baroda, who attended the gathering.

This is the first time in 50 years that the diamond has appeared at auction, and Christie’s expects it to “achieve in the region of $30 million to $40 million.”

“One of the largest and finest pink diamonds in the world, the Princie Diamond carries a fabulous provenance. The rich history, combined with its rare pink hue, conveys a special charm, which will speak to all collectors in the world seeking the best of the best in gemstones,” said Francois Curiel, chairman of Christie’s jewelry department.

The Princie Diamond is part of Christie’s sale of Magnificent Jewels, which will offer nearly 300 pieces, from colored and colorless diamonds to gemstones, natural pearls and signed vintage jewelry.

Sotheby’s to Offer 11-ct. Fancy Pink Diamond

A 10.99-ct. pink diamond that hasn’t been on the market for more than 30 years will be offered at the Magnificent & Noble Jewels sale, being held by Sotheby’s Geneva on May 17. It has a pre-auction estimate of $9 to $16 million.

The diamond features a classic emerald cut, normally associated with white diamonds. This type of cut is highly sought-after when found in rare colors such as pink and blue, Sotheby’s said. This gem, mounted as a ring, has been graded “fancy intense pink,” natural color and VS1 clarity. It’s further assessed to be type IIa, meaning it is almost or entirely devoid of impurities with extraordinary optical transparency. Less than 2 percent of all diamonds in the world are given this grade of purity and most of those diamonds are white.

It is being offered for sale from a private collection.

Colored diamonds are very desirable on the auction market right now. In November 2010, Sotheby’s Geneva set a world auction record for any diamond and any jewel when it sold the 24.78-ct. Graff Pink for $46.15 million.

“I do not remember the market for colored diamonds to have ever been as strong as it is today,” said David Bennett, chairman of Sotheby’s Jewellery Department for Europe and the Middle East.

Rare vivid blue diamond up for sale at NYC auction

NEW YORK — A two-stone ring with a rare triangular blue diamond the size of a quarter on a gold band with baguette-cut diamonds could bring at least $15 million when it is offered at auction in New York next month.

At 10.95 carats, the stone is the largest triangular-shaped fancy vivid blue diamond ever to come to auction, Christie’s told The Associated Press in advance of the Oct. 20 sale. It is paired with a 9.87-carat white diamond cut in the same shape.

“Vivid blue is the strongest and purest saturation in any colored diamond,” said Rahul Kadakia, Christie’s jewelry expert. “As a vivid, this is as good as it gets.”

The two diamonds were cut to be together.

“They are perfectly matched in size and shape. They may be different in terms of weight, but the measurements are perfect. These two stones are made for each other,” Kadakia said.

The Gemological Institute of America said the blue stone in Christie’s sale is the largest triangular-shaped fancy vivid blue diamond they’ve ever graded, Kadakia said.

It is being sold by an anonymous European businessman. Kadakia described him as “someone with a very, very keen eye” who purchased the ring for $1 million from Italian luxury jeweler Bulgari in Rome in 1972 — a gift to his wife for the birth of their son. The couple went on to have three more children, celebrating each birth with an important gift.

Bulgari’s distinctive geometric forms, classic Greek and Roman influences and unusual combinations of colored and colorless diamonds have long adorned celebrities and movie stars, including Grace Kelly, Audrey Hepburn and Elizabeth Taylor.

Last year, a 7.03-carat cushion-cut blue diamond sold at Sotheby’s for $9.5 million, or $1.3 million per carat — setting the highest price ever for a fancy vivid blue gem.

Based on that sale, the Bulgari blue diamond alone is worth $15 million, said Kadakia. With the white diamond, the ring could well surpass that estimate.

The Wittelsbach-Graff Diamond, a 17th-century fancy deep grayish-blue 35.56-carat gem, holds the world record for any diamond and jewel sold at auction. Christie’s sold it in 2008 for $24.3 million.

Worldwide, Kadakia said, blue diamond production accounts for 0.0001 percent of all diamonds produced. And only one in 10 million diamonds have a color pure enough to qualify as fancy vivid blue and measuring over 10 carats.

The blue is determined by trace amounts of boron. The GIA scale runs from faint blue, light blue, fancy light blue, fancy blue, fancy intense blue, deep blue and — when the tonality and saturation are perfect — fancy vivid blue.

The Bulgari blue diamond probably came from the Premier Diamond Mine in South Africa, virtually the only mine in the world producing blue diamonds, Kadakia said. It is where the 3,100-carat rough Cullinan Diamond was found in 1905, and from which the British Crown Jewels the Great Star of Africa and Cullinan II diamonds were cut and polished.

Kadakia estimated that the Bulgari blue diamond came from a rough of at least 20 carats — the rest being lost to polishing.

The world’s largest known deep blue diamond is the 45.52-carat Hope Diamond, discovered in the 1600s, and housed at the Smithsonian.

Kadakia said that in the last 2 1/2 years he has seen a 15-20 percent rise in the number of clients investing in high-end jewelry and diamonds, both those who buy at auction and privately.

“In what other form could you carry $15 million to $20 million so easily?” he asked.

The ring will be officially unveiled at Christie’s Geneva gallery on Tuesday, with stops later in Hong Kong and London before returning to New York.
