Miners claim to have discovered the world's third-largest diamond mine in Africa.

The stone is 1,098 carats, slightly less than the second-largest ever found diamond. According to press sources, miners in Botswana have discovered a spectacular 1,098-carat diamond, which could be the world's third-largest diamond.

According to Bloomberg, the massive stone was discovered on June 1 at the Jwaneng mine in southern Botswana, which is considered the world's most precious mine.

According to a spokeswoman for the mining business, the massive rock is the largest diamond ever unearthed in Debswana's five-decade history.

Debswana is a joint venture between De Beers and the government of Botswana.

The world's largest diamond, Cullinan, is bigger than the two runners-ups, which were found in South Africa in 1905, measuring 3,106 carats. In 1908 the titanic gem was divided into about 100 pieces.

The most significant 530-carat chunk was sent to London and adorning the top of the Royal Scepter by the British Sovereign (one of the Crown Jewels of England stashed in the Tower of London.)

According to Bloomberg, the new stone will be examined in the following weeks, after which Botswana's state-owned diamond the trading company will decide whether to purchase it from Debswana or let De Beers sell it.

According to The Guardian, Botswana is Africa's most significant diamond producer. It is also home to the mine where the world's second-largest diamond, the Lesedi La Rona, was discovered in 2015.
