World’s second-largest diamond found in Botswana

The second-largest diamond ever found – a rough 2,492-carat stone – has been unearthed in Botswana at a mine owned by Canadian firm.

It is the biggest find since the 3,106-carat Cullinan diamond, found in South Africa in 1905 and cut into nine separate stones, many of which are in the British Crown Jewels.

The diamond was found at the Karo-we mine, about 500km north of Botswana’s capital. Botswana’s government said it was the largest diamond ever discovered in the southern African state.
