Colored Diamonds Set to Sparkle at Sotheby’s

6.11 carat, fancy intense blue diamond ring

A blue diamond ring is among the top lots at the Sotheby’s Magnificent Jewels sale in New York next month.
The piece contains a cut-cornered rectangular modified brilliant-cut, 6.11-carat, fancy-intense-blue, VS2-clarity diamond surrounded by round diamonds. It is estimated to bring in up to $6.5 million at the December 7 auction, Sotheby’s said Monday.


A cut-cornered rectangular mixed-cut, 6.69-carat, fancy-intense-pink, VS2-clarity diamond ring with a high valuation of $6 million will also star in the sale, as will a cushion-cut, 3.01-carat, fancy-vivid-blue diamond. The stone, which is set in a ring and flanked by two heart-shaped diamonds, is expected to sell for up to $4.5 million.

Other notable items include a pear-shaped, 62.65-carat, D-color, VVS2-clarity diamond ring with a high price tag of $3.5 million, and an emerald-cut, 9.97-carat emerald and diamond ring with an upper valuation of $2.5 million.


An unmounted, heart-shaped, 15.01-carat, D-color, internally flawless diamond will also be up for grabs. The stone, which is being offered without reserve, has a high estimate of $2.5 million. Sotheby’s is collaborating with Brilliant & Black designer Lauren Harwell Godfrey to make a finished jewelry piece for the diamond, it noted. She has created two original designs that utilize her signature triangle inlay pattern — for a necklace and a ring.


Meanwhile, 30 jewels from an American private collector will also go under the hammer. The entire group is estimated at more than $6 million and includes one of the most significant collections of Bulgari pieces ever to come to market, Sotheby’s explained.

In total, the auction house will offer more than 200 lots, with the sale forecast to fetch as much as $70.1 million — the highest estimate for a New York Magnificent Jewels sale since December 2018, Sotheby’s added.

The Key 10138, the rare pear-shaped diamond, that was auctioned at Sotheby’s on Friday, has been sold for $12.3 million using cryptocurrency. It was sold to an anonymous private collector.

At the time the auction was announced, the piece became the first time a diamond of such size had been offered for public purchase with cryptocurrency. Now it has now become the highest price achieved for any jewelry or gemstone bought with cryptocurrency.

“We are thrilled to witness a historical moment, when one of the Earth’s oldest and rarest treasures was purchased using humanity’s newest universal currency,” said Wenhao Yu, Deputy Chairman of Sotheby’s Jewellery in Asia, in a statement. “By introducing this innovative payment option to our luxury sale, we open up new possibilities and expand our reach into a whole new clientele, many of whom are from the digitally savvy generation. The result today not only attests to the resilient demand for top quality diamonds, but also reinforces Sotheby’s position as a pioneer in the luxury field.”

The 101.38 carat diamond from which it takes its name is the second largest pear-shaped diamond to appear on the public market and came from the world-leading diamond company Diacore, the auction house says.

The Key 10138 has achieved the highest gradings in both colour (D colour – the highest grade for a white diamond) and clarity (completely flawless, both internally and externally). It also belongs to the rare subgroup comprising less than 2% of all gem diamonds, known as Type IIa. Diamonds in this group are the most chemically pure type of diamond and often have exceptional optical transparency.

73ct. Yellow to Shine at Sotheby’s New York Sale

73.11 carat yellow diamond

Sotheby’s will offer a fancy-vivid-yellow diamond ring at its New York sale next month, estimating the piece could fetch up to $3 million.

The cut-cornered square step-cut, 73.11-carat, VS2-clarity jewel by Mayfair designer Glenn Spiro, called The Sienna Star, is one of the largest fancy-vivid-yellow diamonds to come to auction, Sotheby’s said Wednesday. The piece is one of the top items at the June 9 Magnificent Jewels sale. The auction will feature jewelry for the “Roaring Twenties 2.0” as people return to the social scene following long lockdowns, Sotheby’s noted.

A private collection of six jewels with a combined estimate of more than $13 million are another headline lot at the New York sale. Those include a necklace by Andrew Clunn, set with 28 oval-shaped diamonds totaling over 168 carats, which carries a high estimate of $3 million, and an emerald-cut, 23.59-carat, D-color, internally flawless, type IIa diamond ring with an upper valuation of $2.8 million.

A Colombian emerald and diamond garland necklace by Harry Winston, estimated at up to $2.5 million, and a 13.02-carat Burmese ruby ring, mounted by Carvin French, with a $2 million high valuation, are also part of the collection. Proceeds from the sale of those six items will be donated to charity.

Additionally, Sotheby’s will showcase a Bulgari ring with a 25.29-carat Kashmir sapphire flanked by diamonds, which it expects will bring in up to $3 million. Meanwhile, a modified square brilliant-cut, 3.75-carat, fancy-intense-pink, VVS1-clarity diamond ring, accented by triangle-shaped and round diamonds, is estimated to fetch up to $2.5 million.

The auction house will present jewels from the collection of philanthropist Margaret Jonsson Rogers, the daughter of Texas Instruments founder and Dallas mayor J. Erik Jonsson, as well as property from the estate of Mary Ethel Weinmann, the daughter of Count and Countess André de Limur, it added.

A Nearly 64 Carat Diamond Cartier Bracelet Could Fetch HK$40 Million at Sotheby’s

Cartier diamond bracelet

An iconic Cartier bracelet with 63.66 carats of pear-shaped D color, internally flawless diamond set on rock crystal is expected to fetch between HK$40 million and HK$65 million (US$5.16 million and US$8.39 million) at Sotheby’s Hong Kong’s sale of magnificent jewels in April.

Taking nearly 2,000 hours to create, the bangle-bracelet from the collection “L’Odyssée de Cartier —Parcours d’un Style,” pays homage to an Art Deco inspiration featuring sparkling stones and the French maison’s emblematic panther, orchid, and Oriental motifs.

Louis Cartier, the brand’s third-generation jeweler was a pioneer in working with rock crystal, which became popular in the 1920s. Cartier utilized a polishing technique from the Renaissance period to give a soft shine to rock crystal which, when paired with a diamond, creates an intriguing light effect.

The unique piece “combines a phenomenal diamond, mesmerizing design and impeccable craftsmanship, and represents a high jewelry collectible that will shine through time,” Wenhao Yu, deputy chairman of jewelry at Sotheby’s Asia, said in a statement.

Also on offer is “Circle of Happiness,” a bangle made of 277.7 carats of green jadeite-jade from Myanmar. Sotheby’s did not disclose the estimate of this bracelet.

Sotheby’s sale of magnificent jewels will also feature pieces from the houses of Boucheron, Bulgari, Chanel, Chopard, Graff, Harry Winston, Hermès, Van Cleef & Arpels, and more.

“The appetite for high-quality jewels has never been stronger in Asia, with discerning collectors looking for rare diamonds and gemstones, as well as unique and iconic designs,” Yu said.

Cartier Emerald And Diamond Ring Fetches $3.6 Million At Sotheby’s

Emerald

A Cartier emerald and diamond ring blew past five fancy colored diamonds to become the top lot at Sotheby’s New York Magnificent Jewels auction held Wednesday. It fetched $3.6 million, more than three-and-a-half times its high estimate.

The ring features a 21.86-carat Colombian square-emerald-cut emerald flanked by diamonds and mounted on 18k yellow gold. The emerald is described in the grading report as having “minor clarity enhancement” and a “richly saturated medium deep slightly bluish green, slightly included with a few surface reaching inclusions, and the girdle bearing a chip and a few nicks, noticeable under 10x magnification.”

The ring was from the collection of Cecile Zilkha, best known for her lifelong interest in the arts, particularly The Metropolitan Opera.

Private collections featuring a variety of signed jewels were an important part of this sale, with many items from these collections far exceeding estimates. All 29 jewels from the Cecile Zilkha collection sold, fetching a total of $11.7 million, nearly double the estimate for the collection. Eleven jewels from the collection of Marylou Whitney, the philanthropist, thoroughbred breeder, arts patron and society hostess, all sold fetching a total of $1.7 million.

The sale overall was quite successful, taking in a total of $46.9 million, the highest total for a Sotheby’s jewelry auction since 2017. In addition, 91% of the lots sold, with 74% of the lots fetching prices above their high estimates and nine pieces surpassing $1 million.

The first was the anticipated top lot of the sale, a pink gold and platinum ring set with a 5.03-carat cut-cornered rectangular mixed-cut fancy vivid pink diamond, accented with two cut-cornered triangular step-cut fancy intense blue diamonds. Its estimate was $9 million – $12 million.

The second was a ring centered with a 2.28-carat fancy vivid blue heart-shaped diamond, encircled by round yellow and framed by white diamonds with an estimate of $2.25 million – $3.25 million.

The three remaining fancy colored diamond lots sold within estimates and were the next three top lots of the sale. They are:

* A 1.71-carat heart-shaped fancy red diamond with SI2 clarity surrounded by white diamonds and mounted on an 18k white and pink gold pendant for a necklace. It fetched more than $3.1 million.

While Cartier, Bulgari and Harry Winston dominated the headline sales, jewels from Van Cleef & Arpels may have had the biggest impact overall. Twenty-eight jewels by the Parisian luxury brand were sold at the auction. The top lot from Van Cleef & Arpels was a mystery-set sapphire and diamond brooch designed as a flower from a New York collector that sold for more than $1.1 million, nine times its high estimate. That was certainly a headline sale.

An indication that private collections and signed jewels were going to dominate came at the very beginning of the sale. The first 10 lots from a private family collection were by Van Cleef & Arpels. They all sold well above their estimates.

Other auction highlights included:

Sotheby’s Nets $18M at Live New York Jewellery Sale

12.38-carat, fancy-pink diamond ring

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.

102 Carat D Flawless Diamond Fetches $15.6 Million

102.39-carat D-flawless oval diamond

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.

The 118.88-carat Burmese sapphire and the 6.41-carat pigeon’s blood Burmese ruby.

 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.

Sotheby’s is set to auction off one of the rarest diamonds in the world

102.39 carat D Colour Flawless Oval Diamond

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.”

No Buyer for 3ct. Blue Diamond at Sotheby’s

3.01 carat fancy vivid blue diamond

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.
