It was later cut into several stones, including the First Star of Africa and the Second Star of Africa, which are part of Britain’s Crown Jewels held in the Tower of London. Lucara’s 1,109-carat Lesedi La Rona was the second-biggest in record, while the 995-carat Excelsior and 969-carat Star of Sierra Leone were the third- and fourth-biggest.
