De Beers, the company founded by Cecil Rhodes which once controlled over 80 per cent of the world’s rough diamond supply, may soon go up for sale. Finding a buyer will be tricky. Since the pandemic, prices for mined diamonds have fallen by 26 per cent as indistinguishable lab-grown varieties have surged in popularity. Anglo American, De Beers’ parent company, is the target of a $39 billion hostile takeover bid by rival miner BHP. If BHP’s merger plans succeed – an outcome highly dependent on the blessing of South Africa’s government – it will seek to offload De Beers, ideally to a luxury house like LVMH or a buyer from the Gulf. But experts fear oversupply and a crash in the market: research by the antique diamond trader Hatton Jewels found some retailers of lab-grown stones are inflating profits by 1,200 per cent. It’s no surprise valuations for De Beers are all over the place. Anglo says it’s worth $7.6 billion; analysts’ estimates range from $600 million to $4 billion.
