A Flawless 88.22-Carat Oval Diamond Just Sold For More Than $13.7 Million at Auction

The stunning stone is considered "perfect according to every critical criterion."

A stunning 88.22-carat oval diamond just sold at a Sotheby's auction in Hong Kong for a whopping $13.7 million. The oval brilliant diamond is considered "perfect according to every critical criterion," and according to Sotheby's, the stone is internally and externally flawless, has excellent polish and symmetry, and is a D color grade, the highest grade for a white diamond.


The stone is one of only three oval diamonds larger than 50 carats to appear at auction in recent memory, and is the largest seen at auction in more than five years. The diamond was purchased by a private collector from Japan, who named it ‘Manami Star’ after his eldest daughter. The buyer first saw the diamond while it was on exhibit in Japan, and he beat out two other bidders who were also vying for the stone.

The size of the diamond compared to an egg

The gem was thought to receive the highest bid between $11.2 and 12.7 million at the Magnificent Jewels and Jadeite auction, but the final price eclipsed the estimate. The massive diamond originated as a 242-carat rough stone from a mine in Botswana. It was eventually cut and polished into the striking and sizable oval stone it is today.

“We were thrilled to handle a diamond of such rarity, which now takes its place in the roster of top white diamonds to have come to the market here at Sotheby’s Asia," said Patti Wong, Sotheby’s Chairman in Asia. "At 88.22 carats, this lucky stone now carries the name of the fortunate child whose father has chosen to give it her name. A happy moment in the journey of one of the earth’s greatest, oldest treasures."
