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.
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.
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.
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.
1.71-carat heart-shaped fancy red diamond with SI2 clarity fetched more than $3.1 million SOTHEBY’S
Fancy colored diamonds, including three heart-shaped gems, made up the top five lots prior to the sale. However two of the gems failed to meet the reserve price. 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.
3.67-carat fancy intense blue diamond fetched more than $3.1 million SOTHEBY’S

* An 18k white and pink gold ring centered with a 2-carat fancy vivid orange diamond framed and accented by round diamonds that fetched nearly $1.9 million.
As mentioned, private collections were an important part of this sale. In addition to the Cartier emerald ring, the Cecile Zilkha collection comprised of 28 other signed and historic jewels. Among the standouts:

A Cartier natural pearl necklace from the collection of Marylou Whitney fetched more than $1.6 … [+] SOTHEBY’S
The sale ended with 11 jewels from the collection of Marylou Whitney. The top lot in this collection was a Cartier necklace composed of 32 rare natural pearls with a diamond clasp. It fetched more than $1.6 million, more than three times its high estimate.
Emerald, ruby, sapphire and diamond Mughal-inspired necklace by David Webb sold for $327,600 SOTHEBY’S
In addition, two David Webb pieces from the Whitney collection performed extremely well. The first was a platinum bracelet set with 10 emerald-cut diamonds weighing 21.16 carats. It fetched $352,800, above estimates. The second was a showstopper Mughal-inspired necklace that boldly displays a 181.95-carat translucent carved emerald and 10 cabochon emeralds that weigh a total of 126.30 carats, along with rubies and diamonds. The necklace sold for $327,600, more than triple its high estimate.
Van Cleef & Arpels mystery-set sapphire and diamond flower brooch fetched $1.1 million SOTHEBY’S
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:
Jadeite, natural pearl and diamond necklace by Raymond Yard, circa 1935, fetched $1.6 million SOTHEBY’S

* A ring set with a 1.08-carat pear-shaped fancy vivid blue diamond accented by round diamonds sold for $927,500, above estimates. The piece was offered by a Texan collector.
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.
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.

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.
