Among the stones cut from it was the Star of Africa, which is part of the British crown jewels on display in the Tower of London.
Dethroned: Sewelô
The 1758-carat Sewelô diamond was, until Thursday, the second-biggest diamond in history.
It was mined in Botswana, also by Lucara, in 2019.
Luxury group LVMH, owned by Bernard Arnault, previously listed as the world’s richest man, bought the tennis-ball-sized diamond in January 2020.
Lesedi La Rona
The 1109-carat Lesedi La Rona – a diamond also the size of a tennis ball – was discovered at Karowe, northeastern Botswana, also by Lucara in November 2015.
It was bought by British jeweller Laurence Graff for $53 million in September 2017.
