Big diamond rings in $67m

A TENNIS ball-sized rough diamond unearthed two years ago by a Vancouver- based diamond producer has been sold for $67 million.

The 1109-carat stone – the world’s largest uncut diamond – was bought by UK dealer Graff Diamonds, and will be cut and polished.

The price was an “improve– ment” on the highest bid received at a Sotheby’s auction in June 2016, Lucara Diamond Corp chief William Lamb said.

The stone, named “Lesedi La Rona,” or “Our Light” in the language of Botswana where it was mined, is said to be 2.5 to 3 billion years old.
