On the rocks: This De Grisogono necklace features the world’s largest flawless diamond

The autumn auction season is here, and we’ve already witnessed some rather intriguing and record-breaking items going under the hammer. There was the 900-year-old Northern Song Dynasty brush washer that sold for an astounding US$37.7 million (S$51.2 million) within minutes at Sotheby’s — setting a new world record for Chinese ceramics — and a 30-year-old Macallan whisky cask that fetched US$375,000 (S$508,875) at a Spink auction in Hong Kong.

The latest to join the fray is Christie’s upcoming sale of a massive 163.41-carat, D-colour emerald-cut sparkler — the world’s largest flawless diamond to go to auction. Crafted on a necklace designed by Swiss jeweller De Grisogono, the impressive Type IIA rock was obtained, cut and polished from a bigger 404.20-carat rough diamond mined in eastern Angola last year. The latter was the 27th largest rough white diamond ever found.

This rough diamond weighs a whopping 404.20 carats.

What De Grisogono has done is mount the giant diamond on a resplendent, asymmetric necklace festooned with 18 smaller emerald-cut diamonds on the left side. On the other side of the necklace is an eye-popping array of pear-shaped and brilliant-cut emeralds in various sizes, which sweep downward in two rows following a fluid, curved silhouette.

The emeralds and diamonds are meticulously arranged against a darkened gold background in De Grisogono’s signature chiaroscuro style — which highlights the contrasting lights and shadows of the glittering rocks — and culminate in the scintillating, 163.41-carat central stone. We can only imagine how showstopping this jewel will look when paired with a chic little black dress.

The necklace is currently on display at the travelling The Art of De Grisogono exhibition, which previously made stops in Hong Kong and London, and will next be in Dubai and New York. It will make its final stop in Geneva on 14 November, when it goes under the hammer at Christie’s Magnificent Jewels auction. The estimated price has not yet been released yet, but we’re certain a beauty like this will carry a hefty one.
