An impressive flawless 163-carat diamond that has been hailed the “world’s most beautiful” will go under Christie’s hammer in Geneva in November, the auction house said Thursday.
Discovered in February last year in eastern Angola, the 404.20-carat rough diamond — named the “4 de Fevereiro” — was also the largest found so far in the southern African country, Christie’s said.
A team of ten diamond-cutting specialist were involved polishing the rough diamond during the period of 11 months. The stone was then designed into a one-of-a-kind piece by Swiss jewellery house de Grisogono.
The D-color, emerald-cut diamond is classified as a rare Type IIa one, which in technical terms means an almost complete absence of nitrogen in the stone, de Grisogono said in a separate statement.
It took over 1,700 hours to create this unique jewel and involved a team of 14 craftsmen and their know-how as well as love for perfection for each detail in the necklace.
The finished piece, named The Art of de Grisogono, allows customers to detach it from its white gold, diamond and emerald necklace, if they wish to do so. It will be shown in London, Dubai and New York before going to auction in Geneva on November 14.
