Sotheby’s will offer two diamonds weighing more than 100 carats at its upcoming jewelry sale, with one expected to fetch in excess of $10 million.

The Juno diamond, a pear-shaped, 101.41-carat, D-color, internally flawless, type IIa stone, will lead the June 16 New York Magnificent Jewels sale, the auction house said last week. Only 11 D-color diamonds over 100 carats have ever been sold at auction, Sotheby’s noted.

That stone will be joined by the Earth Star, a pear-shaped, 111.59-carat, fancy-deep-orange-brown diamond, which has returned to the auction block for the first time in nearly 40 years. The piece, which is the second-largest diamond of its color, cut and size to be offered at an auction, carries a high estimate of $2.5 million.

Designer David Webb has created a custom mounting for the stone, which was fashioned from a 248-carat rough discovered at the Jagersfontein mine in South Africa in 1967. The setting uses azurmalachite to resemble the Earth as seen from the perspective of a star, Sotheby’s explained.

Other notable items include an emerald-cut, 26.06-carat, D-color, VVS1-clarity diamond ring by Kwiat, which is estimated at up to $3 million, and a pair of diamond and sapphire earrings. The set features two pear-shaped, D-flawless diamonds weighing 4.09 and 4.12 carats; two emerald-cut, D-color diamonds weighing 3.19 and 3.17 carats; and two Kashmir sapphires weighing 9.65 and 9.44 carats. It is predicted to realize up to $3 million. Meanwhile, an Indian-inspired emerald and diamond fringe necklace by Cartier made in 1945 has a price tag of $1.5 million to $2.5 million.

De Beers Cullinan Blue Diamond Could Bring $48M at Auction

De Beers Cullinan Blue Diamond

Sotheby’s will auction a stone described as “the largest vivid blue diamond ever to appear at auction” on April 27 in Hong Kong.

Sotheby’s estimates that it could bring $48 million.

Cullinan Blue Diamond

The 15.1 carat step-cut blue was cut from a rough stone discovered in April 2021. It is “the largest internally flawless step cut vivid blue diamond that the Gemological Institute of America (GIA) has ever graded,” according to a press statement.

“This diamond ranks as one of the best De Beers has ever seen,” said Bruce Cleaver, CEO of De Beers Group. “It is extremely rare and unique, and as the Home of Diamonds, De Beers is pleased to join together with Sotheby’s to bring this diamond to the world.”

Only five blue diamonds over 10 carats have ever come to auction, Sotheby’s notes. Until now, none has exceeded 15 carats.

“Blue diamonds of any kind are rare on the market, but this is the rarest of the rare; nothing of remotely similar calibre has appeared at auction in recent years,” says Patti Wong, chairwoman of Sotheby’s Asia. “Hundreds of millions of years in the making, this extraordinary blue diamond is surely one of nature’s finest creations.”

The diamond comes from the Cullinan mine in South Africa.

Sotheby’s to Offer 39-Piece Lalique Collection

The Lalique Orchidée Cattleya comb.

Sotheby’s will hold a sale dedicated to the works of René Lalique, featuring nearly 40 pieces collected over four decades.

The jewels, which make up a “rare museum-quality collection,” are all appearing at auction for the first time, Sotheby’s said last week. Assembled by Claude Sorbac, one of Lalique’s greatest fans, the grouping is set to go under the hammer on December 17 in Paris.

The Orchidée Cattleya comb, created between 1903 and 1905, is the star of the show. Sorbac bought the piece in 1976 from Lalique’s heirs. The largest of a series of three, and containing diamond-studded foliage, the comb is estimated at up to EUR 1.5 million ($1.7 million).

Other notable items include the Loving Swallows comb, made around 1905 or 1906, which was also purchased from the artist’s descendants. It is valued at EUR 400,000 to EUR 600,000 ($450,660 to $675,906).

Meanwhile, two glass, enamel and diamond necklaces will be up for sale. The first, named Frogs, carries an estimate of EUR 400,000 to EUR 600,000, while the second, called Dragonflies and Ferns, is valued at EUR 250,000 ($281,627) to EUR 400,000.

Tiffany Necklace Breaks Records at Sotheby’s

The Medusa necklace designed by Louis Comfort Tiffany

The Medusa necklace, one of the earliest pieces designed by Louis Comfort Tiffany, sold for more than 18 times its high estimate at a recent Sotheby’s auction.

The piece, designed in 1904, was last seen at auction 78 years ago. It fetched $3.7 million against an upper estimate of $200,000 following 10 minutes of heated bidding, Sotheby’s said Wednesday. The pendant set a world auction record for a piece by the designer. In total, the December 7 Magnificent Jewels sale achieved $57.1 million, the second-highest figure for a jewelry auction at Sotheby’s New York.

Blue diamonds also performed well, with a cut-cornered rectangular modified brilliant-cut, 6.11-carat, fancy-intense-blue diamond ring garnering $8 million, or $1.3 million per carat, well above its high estimate. A ring bearing a cushion-cut, 3.01-carat, fancy-vivid-blue diamond flanked by two heart-shaped diamonds sold for $3.9 million, or $1.3 million per carat, within expectations.

Other notable items include a group of jewels from an American private collector, which features one of the largest private collections of Bulgari pieces ever to come to market, Sotheby’s noted. Some 93% of those items found buyers, realizing $9 million, above their combined $8.2 million high estimate.

Meanwhile, a ring set with a pear-shaped, 62.65-carat, D-color, VVS2-clarity diamond bracketed by two pear-shaped diamonds weighing 2.04 carats and 2.01 carats fetched $2.9 million, in the middle of its presale valuation. A ring containing a cut-cornered rectangular step-cut, 1.03-carat, fancy-red diamond framed by shield-shaped diamonds hammered for $2 million, the upper end of its estimate.

Sotheby’s sold 84% of goods on offer, with 68% of those achieving prices above their high estimates and 13 pieces going for more than $1 million. Participants came from more than 45 countries.

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 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:

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.

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.
