Record Diamond to Lead Sotheby’s $493 Million Hong Kong Auction

The largest diamond of its type offered at auction, Haut-Brion wines and a Chenghua-era porcelain bowl will lead Sotheby’s Hong Kong autumn sales estimated to raise as much as HK$3.8 billion ($493 million).

The oval D-color Flawless Type IIa, 118.28-carat diamond was mined in South Africa in 2011 and is estimated to sell for as much as HK$280 million, the New York-based company said.
