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.
