Sotheby’s Scores over $6M at Hong Kong Jewelry Auction

A sapphire and diamond ring took the top spot at a recent jewelry sale at Sotheby’s in Hong Kong, smashing its high estimate.

The piece, which contains a cushion-shaped, 17.50-carat, royal-blue Burmese sapphire surrounded by marquise-cut diamonds, sold for HKD 2.8 million ($357,226), the auction house said last week. That figure was well above its upper presale price.

In total, the January 31 Important Jewels auction brought in HKD 48.9 million ($6.3 million).

Yellow diamonds performed well at the sale, as did jewels by well-known design houses, including Graff, Cartier, Buccellati, and Van Cleef & Arpels. Sotheby’s also sold several diamonds and both green and lavender jadeite pieces with no reserve.

Here are the other four items rounding out the top five:

This cushion-shaped, 14.51-carat, fancy-intense-yellow, VS1-clarity diamond ring by Bulgari went for HKD 2.5 million ($324,751), within its presale estimate.

 
A ring set with an oval-shaped, 7.02-carat, Mozambican ruby center stone, surrounded by oval and pear-shaped diamonds, fetched HKD 2.5 million, just under its HKD 2.6 million ($332,422) upper price.
Sotheby’s sold this Graff bracelet, featuring nine cut-cornered square or rectangular-modified, fancy-intense-yellow diamonds ranging from 1.62 to 5.21 carats and 18 yellow-tinted diamonds for HKD 2.4 million ($308,513), within its estimate.
A pair of earrings, each suspending an oval ruby — one weighing 4.26 carats and the other 4.09 carats —and brilliant-cut diamonds, garnered HKD 1.9 million ($243,563) at the sale, within its presale price range.

21 ct Yellow Harry Winston Diamond Could Fetch $1.4m

A 21.38 carat Fancy Vivid Yellow diamond is to be auctioned tomorrow (31 January) at Sotheby’s Hong Kong with an estimate of HKD 8,000,000 to 11,000,000 HKD ($1m to $1.4m).

The radiant-cut VS1 gem is flanked by two tapered baguette diamonds, mounted in platinum and 18 karat yellow gold, inscribed HW (Harry Winston).

The FCRF (Fancy Color Research Foundation) gives the stone a visual score of 7 out of 12. It says the stone looks slightly larger in relation to its weight, which is an important feature to consider when buying color diamonds.

“A large vivid yellow radiant cut diamond features a low inner grade and prominent colorless patches around the crown area,” it reports. “No significant green or brown undertone is visible in the hue.”

The stone leads the live Important Jewels auction, Sotheby’s first jewelry auction of the year in Hong Kong, comprising a selection of diamonds, colored stones, jadeites and signed jewels.

94ct. Paraiba Tourmaline to Star in Sotheby’s Sale

Sotheby’s will offer a 93.94-carat Paraiba tourmaline at its upcoming Geneva sale, the largest “top-quality” stone of its kind ever to come to auction, the company said.

The stone, which is set into a bespoke necklace created by Adler Joailliers, will be one of the star lots in the November 8 Magnificent Jewels and Noble Jewels sale, Sotheby’s said Monday. The auction house expects it to fetch between $1.3 million and $2.5 million.

The necklace, called the Blue Lagoon, features a “waterfall” of round and marquise- and pear-shaped diamonds with a total weight of more than 76 carats, the company noted. It will be offered with the original sketch.

Hailing from Mozambique, the stone is distinguished by “an extraordinary electric blue hue,” which recalls the “crystalline waters of a tropical paradise,” Sotheby’s said. Finding Paraiba tourmalines of this size, with such strong saturation and color, is extremely difficult, the auction house added.

Adler is a family business, created in 1886 by Jacques Adler in Istanbul. His grandsons, Franklin and Carlo, opened a boutique in Geneva in 1972. Since 2015, it has been run by the next generation of Adlers — Allen, who is CEO, and his wife, Daisy, who is chief operating officer.

303ct. Golden Canary Sets Sales Soaring at Sotheby’s

303ct. Golden Canary

The 303.10-carat Golden Canary fetched $12.4 million at Sotheby’s Magnificent Jewels in New York on Wednesday, becoming the third most valuable yellow diamond ever sold at auction, the company reported.

The pear-shaped, fancy-deep-brownish-yellow stone is the world’s largest known internally flawless diamond. It is also the largest flawless or internally flawless diamond graded by the Gemological Institute of America (GIA), Sotheby’s said Thursday.  The auction house offered the piece without reserve, but predicted it would bring in more than $15 million.

The diamond was initially discovered in the Democratic Republic of Congo (DRC) in the early 1980s. Originally called the Incomparable Diamond, the stone was recut from its previous 407-carat shield shape to deepen the color and brighten the hue.

“The Golden Canary captivated me from the moment I saw it — with its monumental size, golden hue and impeccable clarity — it is truly an extraordinary diamond with immense presence,” said Quig Bruning, head of jewelry for the Americas at Sotheby’s.

5.53 carat De Beers blue diamond
5.53 carat De Beers blue diamond

A blue diamond weighing 5.53 carats failed to find a buyer at Sotheby’s Geneva on Wednesday despite being billed as the star of the auction.

The cushion brilliant-cut, fancy-vivid-blue diamond is part of an eight-piece group called the De Beers Exceptional Blue Collection, which Sotheby’s has spread between its various Magnificent Jewels sales. No bids matched the stone’s threshold price for sale, according to a post-auction report by the Fancy Color Research Foundation (FCRF). The piece carried a presale estimate of $11 million to $15 million.

“The blue is an exceptional stone in every sense,” Sotheby’s told Rapaport News Thursday. “It attracted significant interest prior to yesterday’s sale. While we didn’t get to see it sell in the room last night, we are confident it will find a new home very soon.”

Meanwhile, a number of items set records at the November 9 sale, including a 20.16-carat sapphire and diamond ring from Cartier. That piece, which fetched $2.8 million against a high estimate of $2 million, saw a record price per carat for any blue sapphire of Burmese origin ever sold at auction. A 20.58-carat, pink sapphire ring also broke the record for per-carat price, bringing in $1.9 million, or $91,690 per carat, well above its $808,368 upper price tag. A pink sapphire and diamond brooch weighing 92.01 carats by Jean Schlumberger sold for $1.8 million, outstripping its $505,278 high estimate and setting a record price for a piece of jewelry by the designer.

Another notable item at the sale was a pair of unmounted oval-cut, D-flawless diamonds weighing 20.03 and 20.19 carats. The duo fetched $4.2 million, within estimates. A step-cut, 33.13-carat, D-color, VVS1-clarity diamond ring by Cartier brought in $2.9 million, also within its expected range.

The entire Geneva Magnificent Jewels auction garnered $50 million. Sotheby’s will offer two more blue diamonds from the De Beers collection at its upcoming New York Magnificent Jewels sale on December 7.

303ct. Polished Yellow to Hit Auction Block at Sotheby’s

Sotheby’s will offer a yellow diamond weighing more than 300 carats at its upcoming New York auction, where it is expected to bring in more than $15 million.

The pear-shaped, 303.10-carat, fancy-deep-brownish-yellow stone is one of the largest polished diamonds in the world. It is also the largest flawless or internally flawless diamond ever graded by the Gemological Institute of America (GIA), Sotheby’s said Monday.

Initially called the Incomparable Diamond, the stone was recut from its original 407-carat shield shape to deepen the color and brighten the hue, and renamed the Golden Canary. As the highlight of the December 7 Magnificent Jewels sale, it will be offered without reserve, with bidding starting at $1, Sotheby’s noted.

The Golden Canary was first discovered in the early 1980s in a pile of rubble by a young girl playing in the backyard of her uncle’s house, Sotheby’s noted. Miners from the nearby Miba diamond deposit had considered the stone to be too bulky to be diamond bearing and had discarded it. The girl gave the 890-carat rough to her uncle, who sold it to local diamond dealers. The diamond has since been displayed in multiple museums.

“The demand and appetite for [extraordinary colored diamonds] continues to grow,” said Quig Bruning, head of jewelry for Sotheby’s Americas. “Steeped in history, the Golden Canary is one of the most exquisite diamonds to ever be discovered, not only for its sheer size and intensity in color, but for its stunning beauty that is sure to captivate collectors around the world.”

Sotheby’s will showcase the diamond on a world tour prior to the auction, with stops in cities including Dubai; Taipei, Taiwan; Geneva; and Hong Kong.

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.
