Sotheby's in Asia will auction off a 72-carat flawless pear-shaped diamond that could fetch up to $15 million.

The diamond, from a southern African mine, is believed to be the third largest "pear-shaped" stone auctioned globally.

Sotheby's says it's a lot of bling for the buck.

"In terms of quality it can't get any better," said Quek Chin Yeow, Sotheby's deputy Asia chairman and its head of jewellery.

The mega-million dollar price tag is expected because of its size, symmetry and class rating, given only to the most brilliant of white D-color diamonds.

"Anything above 50 carats is a major stone. To find a rough of that size and quality and to be able to cut it into a perfect stone is really not an easy thing to do."

But if this rock isn't in your budget, diamond lovers can catch a glimpse of this rare gem as it goes on view at Sotheby's in New York this month. The diamond ultimately goes up for auction on April 10th in Hong Kong.
