A mining company in Botswana has announced the unearthing of a 1,174-carat diamond. It's the second unveiling of a huge diamond discovery in the country in a month.


The latest diamond was discovered on 12 June by Canadian diamond firm, Lucara and presented to the Botswana's in the capital, Gaborone. The company's managing director Naseem Lahri told the AFP news agency that this was the world's third largest diamond.

"This is history in the making, for us and Botswana as well," he said. Last month, a diamond believed at the time to be the third largest - weighing 1,098 carats - was shown to President Mokgweetsi Masisi after the diamond firm, Debswana, unearthed it.

The huge rough diamond that went on sale at auction – which is the size of a tennis ball - was one of three big diamonds found recently after a break of more than a century. Botswana is Africa's largest producer of diamonds.
