Head of Sotheby’s jewellery department in New York, Gary Schuler, commented: “The color is whiter than white, it is free of any internal imperfections, and so transparent that I can only compare it to a pool of icy water.”

The original rough was greater than 200ct and was mined by De Beers in South Africa.
