Sotheby's is no stranger to having rare blue diamonds up for auction.

The diamond's sale price set a world record for the most dollars paid per carat for any diamond or gem.
The diamond, which was originally named the "Blue Moon," was renamed the "Blue Moon of Josephine" by its buyer, Hong Kong businessman Joseph Lau, who renamed the gem after his seven-year-old daughter. He bought the record-breaking diamond a day after purchasing a rare 16.08 carat pink diamond, which he renamed "Sweet Josephine."
