Botswana uncovers huge 2,492-carat diamond that could be one of the biggest ever

The largest diamond found in more than a century has been unearthed at a mine in Botswana, and the country’s president showed off the fist-sized stone to the world at a viewing ceremony.

The Botswana government says the huge 2,492-carat diamond is the second-biggest ever discovered in a mine.

It is the biggest diamond found since 1905.

The as-yet-unnamed diamond was presented to the world at the office of Botswana President Mokgweetsi Masisi on Thursday.

It weighs approximately half a kilogram and Mr Masisi was one of the first to get to hold it.

“It is overwhelming,” Mr Masisi said. “I am lucky to have seen it in my time.”

He gasped and said “wow” before calling senior government officials over to take a closer look.

Officials said it was too early to value the stone or decide how it would be sold.

Another smaller diamond from the same mine in Botswana was sold for 63 million dollars (£48.1 million) in 2016, a record for a rough gem.

“This is history in the making,” said Naseem Lahri, Botswana managing director for Lucara Diamond Corporation, the Canadian mining company that found the diamond.

“I am very proud. It is a product of Botswana.”

Lucara said in a statement Wednesday that it recovered the “exceptional” rough diamond from its Karowe Mine in central Botswana.

Lucara said it was a “high-quality” stone and was found intact.

It was located using X-ray technology designed to find large, high-value diamonds.

“We are ecstatic about the recovery of this extraordinary 2,492-carat diamond,” Lucara President and chief executive William Lamb said in a statement.

The weight would make it the largest diamond found in 119 years and the second-largest ever dug out of a mine after the Cullinan Diamond that was discovered in South Africa in 1905.

The famous Cullinan was 3,106 carats and was cut into gems, some of which form part of the British Crown Jewels.

A bigger, less pure black diamond was discovered in Brazil in the late 1800s, but it was found above ground and was believed to have been part of a meteorite.

Botswana, a country of 2.6 million people in southern Africa, is the second-biggest producer of natural diamonds behind Russia and has unearthed all of the world’s biggest stones in recent years.

The Karowe Mine has produced four other diamonds over 1,000 carats in the last decade.

Before this discovery, the Sewelo diamond, which was found at the Karowe Mine in 2019, was recognized as the second-biggest mined diamond in the world at 1,758 carats.

It was bought by French fashion house Louis Vuitton for an undisclosed amount.
