“The Golden Canary,” a 303.10-carat fancy deep brownish-yellow diamond, will be a highlight of the Sotheby’s Magnificent Jewels auction in New York on Dec. 7, where it will be sold without reserve.
Dubai—News of big fancy color diamonds going to auction keeps rolling in.

Just days after announcing a group of eight blue diamonds, Sotheby’s has unveiled another notable gem: “The Golden Canary,” a 303.10-carat fancy deep brownish-yellow diamond.

Sotheby’s said it’s one of the largest polished diamonds in the world and the largest flawless or internally flawless diamond ever graded by the Gemological Institute of America.

Adding to its notability is its interesting provenance.

The Golden Canary’s story started in the early 1980s, when a young girl playing in her uncle’s backyard in the Democratic Republic of the Congo found it in a pile of rubble.

At the time, miners from the nearby Miba diamond believed the rubble to be too bulky to be diamond-bearing and discarded it, Sotheby’s said. Within it, there ended up being an 890-carat rough diamond.

The Golden Canary is valued at more than $15 million.

The girl gave the stone to her uncle, who sold it to local diamond dealers. 

The public got its first chance to see the rough diamond in 1984 at the Smithsonian National Museum of Natural History where it was on display alongside some of the world’s most notable diamonds and became a global sensation. 

Over the next five years, it was cut into 15 finished stones, the largest of which was a shield-shaped 407.49-carat fancy deep brownish-yellow diamond formerly known as the “Incomparable Diamond.” 

The Incomparable appeared in many museum exhibitions around the world, including “The Nature of Diamonds” at the American Museum of Natural History in New York in 1997, “Diamants” at the Muséum National d’Histoire Naturelle in Paris in 2001, and most recently in “The Nature of Diamonds,” an exhibition that toured The Royal Ontario Museum and the Houston Museum of Science in 2008. 

The stone was eventually recut to maximize the depth of its color, brighten its hue, and improve its shaped, resulting in what’s now being presented as The Golden Canary.

The GIA had this to say about the stone, post-recutting: “The re-cut of the Incomparable to the current 303.10-carat pear modified brilliant is to look at the diamond as new; a re-creation bringing to bear the advances in technology, computer modeling, and visual evaluation available today.  Everything from the orientation of the stone to its shape and cutting style has been considered.”

The Golden Canary will go up for auction during the Sotheby’s Magnificent Jewels auction in New York on Dec. 7.

It’s estimated to sell for more than $15 million but will be offered without reserve, meaning there is no minimum price the seller is willing to accept for the stone. 

The diamond will be showcased on a worldwide tour, starting this week in Sotheby’s galleries in Dubai, followed by cities including Taipei, Geneva, and Hong Kong.  

“We have had an exceptional year of presenting extraordinary colored diamonds at our global jewelry auctions, as the demand and appetite for these rarities continues to grow. Just two weeks after the record-breaking sale of the Williamson Pink Star for $57.7 million, we are honored to offer the largest polished diamond in present existence to appear at auction,” 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 is privileged to help write the next chapter for this incomparable, reborn gem.”
