The Art Of De Grisogono was the most spectacular diamond to ever come to auction, at 163.41 carats it is the largest diamond to ever be offered and the D colour, Flawless clarity and excellent polish and symmetry meant it was pretty much perfect. The rough from which this stunning diamond was born was a 404 carat crystal found in Angola during 2016, it would then embark on 18 month journey which would culminate in the emerald cut diamond gaining worldwide attention and adoration. While it broke the previous world record, many commentators felt it did not achieve its full potential as even though it is considerably larger than the previous record holder the $33 million hammer price did not reflect this.
