A 102.39 carat D-color flawless oval diamond was sold in a single-lot auction at Sotheby's for more than $15.5 million. The sale by Sotheby's Hong Kong was the first time a diamond of more than 100 carats was sold in a combined online and live auction, and it is the first time that such an important diamond was offered without reserve. The diamond was purchased by a private Japanese collector who requested anonymity. With big diamond auctions, one should always remember the 3D's: Debt, Divorce, Death.
