A 15.81-carat diamond could fetch up to $38 million when it goes on sale in Hong Kong next week.
The Sakura — named after the Japanese word for cherry blossom, due to its vibrant hue — is the largest purple-pink “flawless” diamond ever to appear at auction.
The rare stone is set on a simple platinum ring and has been classified as internally flawless, meaning that any blemishes are only visible under close magnification. It has also been classed as being “fancy vivid,” a measure of intense color achieved by only 4% of pink diamonds, according to a press release from Christie’s, the auction house organizing the sale.
Chairman of Christie’s jewelry department, Vickie Sek, said in a phone interview that the stone is “exactly” the shade of a sakura flower. She added that it is “very rare” for pink diamonds to be classified as internally flawless, as they usually contain “a lot of graining.”

The gemstone’s size also makes it an unusual find, with Christie’s noting that fewer than 10% of pink diamonds weigh more than one-fifth of a carat.
Pink diamonds come in various different shades, with stones like the Sakura notable for their purple undertones. While Sek said that “there’s no rule saying (whether purely) pink diamonds or purple-pink diamonds are rarer,” the former are responsible for even bigger sums at auction.
