How Much Would You Pay for the World's Largest Uncut Diamond?

A diamond weighing 1,109 carats has been sold for $53 million

The world's largest uncut gem has been sold to billionaire jeweller Laurence Graff for $53 million, Vancouver-based Lucara Corp. said late Monday, ending the saga of the 1,109 carat stone -- the biggest find in at least a century -- that was recovered two years ago in the southern African republic of Botswana.

"We are thrilled and honoured to become the new custodians of this incredible diamond," Graff said in a statement. "The stone will tell us its story, it will dictate how it wants to be cut, and we will take the utmost care to respect its exceptional properties. This is a momentous day in my career, and I am privileged to be given the opportunity to honour the magnificent natural beauty of the Lesedi La Rona."

Lucara had attempted to sell the Lesedi stone last year at London's Sotheby's auction house, but failed to find a buyer at the then-estimated price of $70 million.
