Founder Fawaz Gruosi described the gem as "the most lovely diamond in the world". And this was validated at the Christie's event in Geneva.
The largest-ever D-flawless diamond to be put up for auction, the "Creation 1", sold for $33.7 million Tuesday night during an auction at Christie's in Geneva. It took more than 1700 hours to create.
The left side of the necklace is made up of 18 emerald-cut diamonds and the right side composed of two rows of pear-shaped emeralds. It has been set in a necklace which has been called The Art of de Grisogono. Not surprisingly, the intricately designed necklace was desired by many and exceeded the pre-sales prediction of $30 million.

A team of 10 specialists in NY cut the jewel from a rough 404-carat stone discovered in Angola previous year, the biggest diamond ever found in that country.
"To date, this is the largest D flawless diamond ever to appear for sale at auction", Christie's said when it first announced the gem would be part of its annual Magnificent Jewels sale.
Diamond cleaver Ben Green analysed the gem for months and eventually started working on splitting the rough diamond in two in June past year.
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.
Founder of the Swiss jewellery maker, Fawaz Gruosi, has described the gem as "the most lovely diamond in the world".
However, he said it gave him "quite a big headache".
