A 5-carat fancy vivid blue diamond named "Ai" — the Chinese word for love — will be flirting with a world record when it hits the auction block at Sotheby's Magnificent Jewels and Jadeite event in Hong Kong on October 3.
The auction house is estimating that the richly colored step-cut gem will sell in the range of $12.4 million to $15.2 million, potentially putting the per-carat price at $3 million or more. If The Ai Diamond outperforms Sotheby's estimate, it will be ascending into the rarefied air occupied by two of the most famous blue diamonds of all time.
Back in May of 2017, the “Oppenheimer Blue” — a 14.62-carat fancy vivid blue diamond — fetched an astounding $57.5 million at Christie’s Geneva. The Oppenheimer Blue’s per-carat price of $3.93 million came up just shy of the record of $4.03 million held by the 12.03-carat Blue Moon of Josephine, another magnificent blue diamond that sold for $48.5 million at Sotheby’s Geneva in November of 2015. It was the highest price per carat ever paid for a diamond or gemstone.
“Fancy Vivid” is the ultimate color classification for blue diamonds. Those displaying lower levels of color saturation may be rated “Fancy Intense,” “Fancy,” “Fancy Light” or “Light,” according to the Gemological Institute of America (GIA). Blue diamonds owe their color to the presence of boron in the chemical makeup of the gem.
The Ai Diamond, which earned a VS2 clarity rating from the GIA, is framed by white baguette diamonds and set in 18-karat white gold.
