Record-breaking, 163-carat diamond unveiled before world tour and auction

A record-breaking, 163-carat diamond was unveiled in Hong Kong on Thursday by Swiss luxury jeweler De Grisogono.

The largest of its kind, flawless and colorless diamond was cut from a 404-carat stone called the “4 de Fevereiro,” discovered in 2016 in Angola, the jeweler announced.

A team of 14 master jewelers and setters worked diligently over 1,700 hours to create by hand an asymmetrical necklace featuring the emerald-cut diamond, according to De Grisogono.
