Golden Canary: The largest pure diamond ever graded
In addition to being one of the largest polished diamonds in the world, the Golden Canary is the largest pure diamond ever graded by the Gemological Institute of America.
Sotheby’s will auction it in its Magnificent Jewels sale on December 7. His estimate is $15 million and he’s being offered without reservations, with bids starting at just $1 million.
This is also the latest in a wave of very high quality colored diamonds that have been auctioned off this year. A bit reminiscent of a period from 2015 to 2018, when exceptional colored diamonds were sold for record prices.
The Golden Canary was formerly known as the Ineffable Diamond, a fancy deep yellow step-cut natural diamond weighing 407.48 carats. The diamond once belonged to the luxury brand Mouawad, owned by a family of Lebanese origins with offices in Dubai and Geneva.
The diamond was re-cut in the classic diamond drop shape (similar in shape to a pear) for the occasion of this sale. Sotheby’s describes the freshly cut gem as having a very elegant profile with an intense and brilliant yellow color in tone.
The cut of the Ineffable Diamond at 303.10 carats was determined to give new life to this diamond, based on the most modern computer cutting and modeling technologies. “Everything from the stone’s orientation to its shape and cut style was considered,” said the Gemological Institute of America (GIA).
