The as-yet-unnamed diamond weighs about a half a kilogram (1.1 pounds). 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.

It’s too early to determine this stone’s value or decide how it will be sold, officials said. A smaller diamond from the same mine in Botswana was sold for a record $63 million in 2016.
With a population of 2.6 million people, Botswana is second only to Russia in natural diamond production – all of the world’s biggest diamonds have been found in the south African country in recent years.
