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, on Wednesday.

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 on 1 June.

President Masisi has shared photos of the latest precious stone as it was presented:
