[10] De Beers discovered the kimberlite A/K6, but their early evaluation showed low economic importance, the mine having only a 3.4-hectare surface area.

In 2009, De Beers sold their 70% shareholding in the mine to Canadian company Lucara Diamond for $49 million.

[10] The company uses modern equipment, giving them the ability to recover large diamonds that the mine has become known for.

[10] One piece of equipment is X-ray Transmission (XRT) technology, introduced in 2015,[10] which later resulted in the recovery of a number of diamonds over 300 carats or 60 grams each.

[15] Currently, it is the second-largest gem-quality diamond ever found[16] and, according to the government of Botswana, the largest ever discovered in the country.
