A small Canadian diamond company has found what it says is the world's second-biggest gem-quality diamond ever recovered, and the largest in more than a century, Reuters reported.

Lucara Diamond Corp. said Wednesday the 1,111-carat stone was found at its Karowe mine in north-central Botswana, one of the world's most prolific diamond-producing areas.

The Type IIa diamond measures 65 millimeters by 56 mm by 40 mm.

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.
