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 colour and brighten the hue, and renamed the Golden Canary. As the highlight of the December 7Magnificent Jewels sale, it will be offered without reserve, with bidding starting at $1, Sotheby’s noted.
