A 163.41-carat D flawless diamond, described as the largest ever put up for auction, was unveiled in Hong Kong on Thursday.
‘D’ graded diamonds are colorless.
The diamond, unveiled by jewelry specialist de Grisogono, is cut from a 404.2-carat stone named the “4 de Fevereiro” that was discovered in Angola in February 2016. The stone is the 27th largest rough white diamond ever discovered and the largest in Angola, according to de Grisogono.
After analysis in Antwerp, the rough diamond was cut in New York, where a team of 10 specialists turned it into a 163.41-carat emerald-cut stone.
De Grisogono then suspended the stone from a diamond baguette necklace, from which it can be detached. The finished jewelry piece, named The Art of de Grisogono, will now be taken on a world tour, visiting London, Dubai and New York before it goes up for auction in Geneva, Switzerland on Nov. 14.
An uncut diamond the size of a tennis ball sold for $53 million Tuesday. British jeweler Graff Diamonds bought the 1,109-carat stone, the Lesedi La Rona, which was mined in Botswana in 2015.
