A diamond produced from a diamond mined two years ago in South Africa was auctioned in Hong Kong for HK $ 238.68 million ($ 30.8 million).
Bloomberg reported that an impeccably pure 118.28 carat diamond-oval cut diamond was the largest stone ever to be auctioned.
According to forecasts, the diamond could go under the hammer at a price of 280 million Hong Kong dollars ($ 36 million).
The auction house Sotheby's can not disclose the identity of the buyer and diamond cutter, saying only that the stone was tested in accordance with all the requirements of the Kimberley Process, as well as the provisions of the US Clean Diamond Trade Act.
