Boko said the governments of Namibia and Angola would participate in the De Beers transaction.
Swiss luxury group Richemont, owner of Cartier, is among companies in talks to join the Global Diamond Consortium.
Anglo American said on Monday it would continue to work with Botswana, other governments and the Global Diamond Consortium towards agreeing binding transaction documents.
MOVING BEYOND THE TRADITIONAL DIAMOND MARKET
Botswana’s stake in De Beers gives it exposure not only to natural diamonds but also to advanced technology through Element Six, the miner’s synthetic diamond business, Boko said.
“Our investment in De Beers is not just an investment in natural diamonds. It is an investment in technology,” he said.
Boko confirmed that Element Six will participate in a planned $600 million synthetic diamond plant that Reuters reported in January will be built in the US.
Demand for synthetic diamonds used in high-performance computing is likely to rise as artificial intelligence and large-scale data centres expand, creating new opportunities beyond the traditional diamond market, the president added.
The US government had asked Element Six to partner on synthetic diamond technology, Boko said. He said he had agreed with US Commerce Secretary Howard Lutnick that the company should form the core of a new technology partnership between Botswana and the United States.
