102.39 carat D-FL diamond sellls for $15.7 million
First diamond of this quality to be sold without a reserve. First bid was 13 cents
"Cut from a rough diamond discovered in 2018 in Ontario, Canada, the oval stone received the highest bid placed for a jewel online, nearly $11 million, but eventually went to a telephone bidder in Japan, a private collector who quickly called the stone "Maiko Star" after one of his daughters. This same collector purchased a diamond from Sotheby's last year, naming it "Manami Star" after his eldest daughter."
