And this was validated at the Christie's event in Geneva.

"The "sensational" 163.41-carat flawless diamond, suspended from an emerald and diamond necklace called The Art of Grisogono, will be one of the highlights at the Christie's autumn jewel auction". Christie's said that the designer took more than 1,700 hours to make to make the necklace.

The buyer's identity has not been revealed. This is the first time that the spectacular diamond has been sold at public auction since the famous sale of the French Crown Jewels in 1887.

It was the largest flawless D-color diamond ever to come to auction.

The original, 404.20 carat rough diamond that was mined in eastern Angola - the 27th largest rough white diamond ever discovered.

Diamond cleaver Ben Green analysed the gem for months and eventually started working on splitting the rough diamond in two in June a year ago.

The colourless diamond was then analysed for many months by diamond cleaver Ben Green.

The rough was analysed in Antwerp and cut in NY, where a team of 10 diamond-cutting specialists were involved in mapping, plotting, cleaving, laser-cutting and polishing the giant rough rock into a polished, flawless diamond.

The diamond, the centrepiece of an asymmetric gem-studded necklace designed by Fawaz Gruosi, founder of Geneva jeweller De Grisogono, exceeded the auction house's expectation of US$25 million.

It went under the hammer at Geneva's Four Seasons Hotel following a series of public viewings in Hong Kong, London, Dubai and NY. He also said that it also gave him a big headache as there was an enormous pressure of "dressing" such an incredible diamond and doing something out of the box, as reported by Sky News.
