Sotheby’s garnered $17.9 million from its Important Jewels sale in New York, with a pink-diamond ring taking the top spot.
The pear-shaped, 12.38-carat, fancy-pink, VVS2-clarity diamond ring fetched $4.6 million, or $373,337 per carat, falling within the price range the auctioneer had estimated. It led the auction house’s first live jewelry sale in the state since the coronavirus pandemic began in March.
“This auction was presented in a new and innovative format, a hybrid of online advance bidding, culminating in the drama of a live auction,” Kendall Reed, head of fine and online jewels at Sotheby’s New York, said last week.
A necklace, set with a pear-shaped, 51.92-carat, D-color, internally flawless diamond pendant, surmounted by a separate pear-shaped, 3.65-carat, fancy-brownish-orangey-pink diamond, went for $3.2 million, just above the low end of its presale valuation. Meanwhile, a diamond ring containing a cushion-cut, 19.24-carat Kashmir sapphire achieved $1.5 million, matching its low estimate.
Some 60% of items on offer sold over their high estimates, including a pink-tourmaline and diamond clip brooch by Schlumberger for Tiffany & Co., which brought in $37,800, more than double its high estimate. A ring featuring a 14.06-carat Burmese ruby went for $302,400 against a high estimate of $140,000, while a star sapphire and diamond ring sold for $52,920, more than four times its $12,000 high presale valuation.
In total, Sotheby’s sold 83% of items on offer, with participants hailing from 30 countries. Three-quarters of buyers placed their bids online.
“Our results are a clear indication that the appetite for top-quality diamonds, rare gemstones and stylish signed jewels remains strong,” Reed added.
A 102.39 carat D color flawless oval diamond was sold in a single lot auction for more than $15.6 million. The sale by Sotheby’s Hong Kong was the first time a diamond of more than 100 carats was sold in a combined online and live auction and such an important diamond was offered without reserve.
The diamond was purchased by a private Japanese collector who requested anonymity, Sotheby’s said in a statement. The person named the gem, “Maiko Star” after his second daughter. The same collector bought the 88.22 carat “Manami Star” at Sotheby’s in April 2019.
The sale of the Type IIa diamond the purest and rarest kind of mined diamond resulted in the highest price achieved for a diamond sold online and earned the most bids for a world class diamond. In addition, it was only the eighth diamond of more than 100 carats ever sold at auction. The auction house describes the diamond as “perfect,” not only because of its top color and clarity grades, but also for its “excellent polish and symmetry.”
However, the total price fell far short of what similar diamonds sold for at auction.
Sotheby’s will sell a 118.88-carat, royal-blue, unheated Burmese sapphire in Hong Kong next week, the largest of its kind the auction house has offered in 20 years.
The cushion-shaped stone, surrounded by pear-shaped diamonds weighing a total of 16.06 carats, will lead the October 7 Magnificent Jewels sale, Sotheby’s said Monday.
A pear-shaped, 4.84-carat, fancy-vivid-blue, internally flawless diamond ring is also set to go under the hammer. The piece, which also features two brilliant-cut diamonds, each weighing 1.10 carats, has a high estimate of $8.5 million.
Also up for auction are a pair of pendant earrings featuring brilliant-cut, fancy-intense-blue diamonds weighing 1.95 and 1.63 carats. Those stones suspend two pear-shaped, D-color, internally flawless, type IIa diamonds weighing 5.95 and 5.24-carats. The set has a presale value of up to $4.6 million.
In addition, Sotheby’s will feature a cushion-shaped, 6.41-carat, pigeon’s blood Burmese ruby ring surrounded by French-cut white diamonds. The jewel, which was designed and mounted by Hong Kong-based jeweler Forms, carries an upper estimate of $2.9 million. Meanwhile, a ring containing a cut-cornered rectangular modified brilliant-cut, 18.68-carat, fancy-light-purplish-pink diamond is set to fetch up to $2.2 million at the Hong Kong sale.
“The jewelry market has proven to be highly resilient, with our clients in Asia eyeing the best quality jewels on offer,” said Wenhao Yu, Sotheby’s deputy chairman of jewelry for Asia.
Sotheby’s will showcase the pieces in Hong Kong from October 3 to 6 prior to the sale.
Sotheby’s is set to auction off a 102 carat diamond that could become the most expensive jewel ever sold to an online bidder.
The stone, a 102.39 carat D Colour Flawless Oval Diamond, could fetch $10 million to $30 million. Only seven flawless white diamonds of more than 100 carats have ever been sold at auction. It is the second-largest oval diamond of its kind ever sold at auction.
“One hundred-carat diamonds as a rule are exceedingly rare,” said Quig Bruning, head of Sotheby’s jewelry department in New York. “One hundred-carat D flawless are even more rare.”
While Sotheby’s doesn’t have an official estimate, comparable diamonds have sold for between $11 million and $30 million in the past, Bruning said.
The stone, described by Sotheby’s as “the size of a lollipop,” will be sold at a live auction in Hong Kong on Oct. 5, but it will also be open to online bidders starting on Tuesday. If it’s purchased by an online bidder, it would likely top the record for the most expensive piece of jewelry ever sold online a pair of fancy blue and pink diamond earrings that sold for $6 million online in 2016.
The 102 carat stone was cut from a 271 carat rough diamond that was discovered in the Victor Mine in Ontario in 2018. The diamond was cut and polished over the course of a year by Diacore to bring out its “best brilliance, fire and scintillation,” according to Sotheby’s. The stone belongs to an elite subgroup of diamonds known as “Type IIa,” which are the most chemically pure type of diamond with the highest level of transparency.
Demand for the rarest, largest diamonds has strengthened during the coronavirus pandemic, as the wealthy have benefited from stronger stock markets and investors look for long-term stores of value in a financial world awash with cash.
While demand for everyday jewelry sold in stores has plunged since people aren’t visiting malls and shops as often, or wearing jewelry as often prices for so-called investible diamonds have remained strong. Wealthy buyers, especially in Asia and the Middle East, covet diamonds as the ultimate hard-asset, since they are durable and portable.
Sales of jewelry and diamonds online have also increased, as people buy more from home. Sotheby’s said its online jewelry sales have totaled $31 million this year, seven times more than the same period last year. It has sold three lots for more than $1 million online.
“The retail experience going into the store, trying things on that’s gone right now, or at the very least has changed substantially,” Bruning said. “A lot of things have moved online, and we have been able to really capitalize on that by showcasing things in a new and compelling kind of way globally.”
When asked whether the buyer of a 100 carat diamond would ever wear it, he said: “Absolutely. They want to enjoy them.”
A 3.01-carat, fancy-vivid-blue diamond ring, carrying a high estimate of $6.3 million was among a number of headline items that failed to find buyers at Sotheby’s Geneva auction.
Sotheby’s withdrew the stone from Tuesday’s Magnificent Jewels and Noble Jewels Part II at the request of the consigner, it told Rapaport News Wednesday. The sale, which achieved a total of $12.4 million, was the auction house’s first live event since the onset of the coronavirus pandemic, and followed Part I, which took place online.
An oval-shaped, 21.56-carat, D-color, VVS1-clarity diamond ring by Lorraine Schwartz, valued at $1.5 million to $2 million, also went unsold. Other colored diamonds were not purchased, including a duet ring set with a pear-shaped, 3.03-carat, fancy-intense-blue diamond and a pear-shaped, 2.82-carat, D-color, VVS1-clarity diamond, as well as a step-cut, fancy-vivid-yellow diamond ring weighing 16.43 carats.
Meanwhile, the top-selling lot at the sale was a marquise-shaped, 7-carat, fancy-intense-pink diamond ring, which was auctioned for the first time after spending 30 years in a private collection. The piece sold for $2.8 million, within its $2.4 million to $3.4 million estimate.
Other notable items included a pear-shaped, 5.29-carat, fancy-grey-blue diamond ring, which garnered $2.1 million, beating its $1.2 million high estimate. A pair of cushion-shaped, D-color, VVS2-clarity diamond earrings, weighing 13.50 carats and 13.52 carats, fetched $1.5 million against an estimate of $1.2 million to $1.8 million.
Sapphires also proved popular, with a cushion-shaped, 105.89-carat ring going for $1.7 million, more than double its $670,000 high estimate. A cushion-shaped, 16.11-carat sapphire ring bracketed by diamonds also sailed past its $490,000 upper valuation, achieving $524,000.
Live jewelry auctions are returning with the first one being held in Geneva by Sotheby’s on June 23 offering a diverse collection of statement diamonds, colored gems and historic jewels.
Sotheby’s Part II Magnificent Jewels & Nobel Jewels – Geneva sale was originally scheduled for May but was postponed due to the novel coronavirus pandemic. The effects of the worldwide spread of this infectious disease is still being felt as dramatically reduced travel and freight shipments have hampered the efforts of jewelry specialists to assess gems and jewels. Most likely because of this and the scheduling changes the sale consists of only 48 lots, far fewer than usual for a live international auction. However, there will be a strong and varied selection gems and jewels.
The live sale is accompanied by an online auction, Sotheby’s Part I Magnificent Jewels & Nobel Jewels – Geneva, with 178 lots dating from the 19th century through to the present day. It includes jewels from renowned jewelry houses, including Sterlé, Suzanne Belperron, René Boivin and Hemmerle. This sale has begun and will run till June 24.
Not surprisingly colored diamonds are among the top lots in live sale, with blues, pinks and yellows dominating. The auction is led by a 3.01-carat fancy vivid blue step-cut, diamond. The colored gem set on a ring has a clarity grade of VS1 (very small inclusions), according to the Gemological Institute of America report. Its estimate is $4.3 – $6.3 million.Most Popular In: Watches & Jewelry

It is set on a ring flanked by fancy-shaped diamonds and with a shank lined with brilliant-cut diamonds. It’s the first time this diamond has come to auction in more than 30 years, where it has been kept in the same private collection. Its estimate is $2.5 – $3.5 million.
There’s also a selection of large, colorless diamonds led by a 21.56-carat D color, VVS1 clarity diamond by Lorraine Schwartz, an American bespoke high jewelry designer with a large celebrity clientele. The gem has excellent polish and symmetry, according to the GIA report.
The Duchess of Manchester’s emerald and diamond necklace, estimate: $300,000 – $400,000 SOTHEBY’S
Among the noble jewels in the sale, the standout is an emerald and diamond necklace owned by Consuelo Montagu (1853-1909), Duchess of Manchester, which was given to her as a wedding gift. Born in New York to parents of Cuban descent, she was known for her match-making skills, inspiring her wealthy friends to find suitable husbands in the United Kingdom, according to the auction house. Her ability to bring together American fortunes with noble titles led to the coining of the phrase “Million Dollar Princesses.” This antique jewel was displayed at the Victoria & Albert Museum in London for 22 years. Its estimate is $300,000 – $400,000.
Cartier diamond bracelet and pair of diamond clips, circa 1930 SOTHEBY’S

The gem is accompanied by reports from the Swiss Gemmological Institute (SSEF) and from Gübelin that both state that there are no indications of heating, with “a few minor nicks and chips consistent with normal wear.” Its estimate is $500,000 – $700,000.
The second is a 16.11-carat Kashmir sapphire set on an 18k gold and diamond ring. The gem is accompanied by two reports from the Swiss Gemmological Institute and from Gübelin that both state that there are no indications of heating and in “very good condition.” Its estimate is $300,000 – $500,000

A 10.64 carat pink diamond ring worth up to $25.5 million will go under the hammer at Sotheby’s Hong Kong sale.
The fancy vivid purplish pink center stone is internally flawless, the auction house told Rapaport News Friday. Sotheby’s will offer the piece, which is flanked by white diamonds, at its Magnificent Jewels and Jadeite sale on October 7. The ring has a presale estimate of $19.1 to $25.5 million USD.
Pink diamonds have historically done well at auction, with the Pink Promise, a 14.93 carat, fancy vivid pink, fetching $32 million USD at Christie’s Hong Kong sale in 2017. In November, Harry Winston purchased the Pink Legacy, an 18.96 carat, fancy vivid pink diamond, at Christie’s Geneva auction for $50.4 million USD.
Prices of pink fancy color diamonds increased 0.4% in the three months ending June 30, outperforming blues and yellows, the Fancy Color Research Foundation noted. The imminent closure of Rio Tinto’s Argyle mine in Australia has contributed to the price rise, as the deposit produces most of the world’s pinks, explained Alan Bronstein, president of the Natural Color Diamond Association.
A flawless 88.22 carat diamond fetched more than $13.7 million at the Hong Kong Sale of Magnificent Jewels and Jadeite held Tuesday.
The total, which includes commissions and fees, surpassed the high estimate of $12.7 million. The D color, type Ila, oval brilliant diamond was the top lot in the sale of 2oo items.
A Japanese private collector purchased the stone and named it the “Manami Star,” after his eldest daughter.
“We were thrilled to handle a diamond of such rarity, which now takes its place in the roster of top white diamonds to have come to the market here at Sotheby’s Asia,” said Patti Wong, Sotheby’s chairman in Asia.
Sotheby’s will offer the historic Farnese Blue diamond at its Geneva sale in May, the first time it has been on the market.
The pear-shaped, 6.16-carat, fancy dark grey-blue stone — originally given to Queen Elisabeth Farnese of Spain as a wedding gift following her marriage to King Philip V in 1714 — has spent 300 years in the private collection of Europe’s royal families. The diamond will go under the hammer at the Magnificent Jewels and Noble Jewels auction on May 15 with an estimated price of $3.7 million to $5.3 million. Originating in the Golconda mines of India, it has traveled from Spain to France, Italy and Austria over the last three centuries.
The family kept the diamond in a secret royal casket, and, other than family members and the royal jewelers, no one knew of its existence.
“With its incredible pedigree, the Farnese Blue ranks among the most important historic diamonds in the world,” said Philipp Herzog von Württemberg, chairman of Sotheby’s Europe and managing director of Sotheby’s Germany.
Queen Elisabeth passed the Farnese Blue to her son Philip, duke of Parma, whose son Ferdinand inherited it and passed it to his son Louis I, king of Etruria. Louis’s grandson, Charles II, duke of Lucca, passed it to his grandson, Robert I, the last ruling duke of Parma, who took the stone from Italy to Austria. He then mounted the stone on a diadem that had belonged to his mother, Louise Marie Thérèse of Artois. Upon the death of Robert I, the stone passed to his son Elias of Bourbon, duke of Parma. His wife, Maria Anna von Habsburg — who died in 1940 — recorded the stone’s history.
The Farnese Blue will appear at Sotheby’s in Hong Kong, London, New York, Singapore and Taipei, before coming to Geneva for display prior to the sale.
To celebrate its one year anniversary, this morning Sotheby’s Diamonds revealed its most exceptional gem to date: a 102.34 carat, D Flawless, Type IIA round brilliant diamond, which the auction house describes as “the rarest and most valuable white diamond ever to come to market”.
The diamond was cut from a 425-carat rough mined by the De Beers group in Botswana. The cutting process took over six months and required the diamond to be transported between Johannesburg and New York.
