A "perfect" diamond said to be so large that it draws awe-struck people across a room has sold for $22 million at a Sotheby's auction in New York.

The 100-carat, emerald cut, D color, internally flawless diamond is the largest of its clarity and cut to ever be shown at auction.

"People everywhere have been drawn to it from across the room and they are in awe of its size, particularly when they put it on their hand," said Gary Schuler, the head of Sotheby's jewelery department in New York, before the sale. "They can't believe there's a diamond this pure of such impressive scale."

A flawless D-color diamond weighing 101.73 carats will be offered as part of Christie’s International’s jewelry auction at the Four Seasons Hotel des Bergues in Geneva, Switzerland on May 15, 2013. The pear-shaped gem, which is the largest colorless diamond of such high quality to appear at auction, is estimated to garner about $20 million. An anonymous client is selling the rare stone that was recently cut from a rough diamond weighing 236 carats found at the Jwaneng mine in Botswana. Workers spent 21 months polishing the jewel.

While colorless stones tend to be less desirable than their colored counterparts, the record price for a colorless stone at auction is $21.5 million, which was set by the 76.02 carat cushion-shaped Archduke Joseph Diamond that sold at Christie’s in Geneva in November 2012. The diamond heading to Christie’s in May is not only the largest colorless stone but also a chemically pure Type IIA diamond, which accounts for less than 2% of the world’s diamond production.

The buyer of the pear-shaped diamond will have the honor of naming the extraordinary jewel, securing its identity among the most desirable diamonds in the world.
