Lucara Diamond firm has announced that a 1,111ct stone – the world’s second-largest gem quality diamond – has been discovered at the Karowe mine in Botswana.

The 1,111ct diamond, described as slightly smaller than a tennis ball, is the biggest stone to be discovered in Botswana and the largest diamond find in over a century. The stone measures 65mm by 56mm by 40mm in size.

The striking piece was recovered from Lucara Diamond’s Karowe mine, about 500km (300 miles) north of the capital, Gaborone.


William Lamb, the chief executive of Lucara Diamond said: “This historic diamond recovery puts Lucara and the Karowe mine amongst a select number of truly exceptional diamond producers. The significance of the recovery of a gem quality stone larger than 1,000 carats, the largest for more than a century and the continued recovery of high quality stones from the south lobe, cannot be overstated.

“Our focus on mining the south lobe, which is delivering value beyond expectation, has been perfectly timed with the commissioning of our recent plant modifications, enabling the recovery of these large, high quality exceptional diamonds.”

An 813ct diamond was also found in the same mine this week, taking the place as the sixth largest gem quality diamond ever mined.

The largest diamond ever found is the 3,106ct Cullinan discovered in 1905.
