LONDON: Anglo American's De Beers said on Thursday it had tracked 100 high-value diamonds from miner to retailer using blockchain, in the first effort of its kind to clear the supply chain of impostors and conflict minerals.
De Beers, the world's biggest diamond producer by the value of its gems, has led industry efforts to verify the authenticity of diamonds and ensure they are not from conflict zones where gems may be used to finance violence.
