(Bloomberg) — How much does the head of the company that unearthed the second-biggest ever diamond want for the gem? More than $60 million, that’s all he’ll say.
“I haven’t even told my wife,” said William Lamb, chief executive officer of Lucara Diamond Corp., which last week announced the discovery of the 1,111 carat gem-quality diamond. It’s “higher than the current estimates that people are putting out there, which are north of $60 million.”
The discovery sent shockwaves through the $80-billion diamond industry. The type-IIa stone, just smaller than a tennis ball, is the biggest unearthed since the 3,106-carat Cullinan gem found in South Africa in 1905. That was cut into pieces, which are set in the Crown Jewels of Britain.
Exceptionally large rough diamonds can sell for about $60,000 per carat, though Lamb hopes that its status will boost its value.
“A lot of people will use use $60,000 a carat as the basis,” Lamb said. “On top of that, you have to look at the size of the final polished diamond as well as the historical context. That’s going to play into it too.”

The CEO, who has already turned down an offer of more than $40 million, said the company has been approached by London’s Natural History Museum about displaying the stone and the Discovery Channel who are interested in making a documentary about it.
“The diamond sector is not full of opportunities, so for us to run out and sell it now doesn’t really make sense,” Lamb said. “We have the time to look at what is the best way to sell it. Not selling it is actually an option.”
Lucara’s Karowe mine in Botswana rivals Gem Diamonds Ltd.’s Letseng operation in Lesotho as the place to find the biggest and best stones.
