The Art of de Grisogono
A diamond necklace featuring a flawless 163-carat diamond – the largest of its kind to be auctioned – sold for $33.5 million at Christie’s in Geneva. The colourless diamond was taken from a 404-carat stone found in Angola. The finished piece, made from white gold, diamond and emeralds, was designed by Swiss jewellery maker de Grisogono. It took more than 1,700 hours to make.
The necklace, named The Art of de Grisogono, sold for $29.5 million plus $4 million premium – exceeding pre-sale predictions of $30 million. The auction followed a series of public viewings in Hong Kong, London, Dubai and New York.
