The Blue Moon Diamond, Sotheby's Geneva

The Blue Moon Diamond, a 12.03ct internally flawless vivid blue diamond, was sold at auction today for $48.4 million by Sotheby's Geneva. The cushion cut stone is one of the few blue diamonds with a fancy vivid GIA grade. The video of the process to cut the rough is very interesting, I hope you enjoy it.
