A small Canadian diamond company has announced the discovery of the world's second-biggest gem-quality diamond ever recovered.
Lucara Diamond Corp. said the 1,111-carat stone was found at its Karowe mine in north-centralBotswana.
The Type IIa diamond measures 65 millimetres by 56mm by 40mm.
The biggest gem-quality diamond ever found is the Cullinan diamond, a 3,106-carat stone found in the Premier mine in South Africa in 1905.
It was cut into several polished gems, the two largest of which are part of Britain's crown jewels.
