The artisanal and small-scale mining (ASM) sector is in need of formalisation in order to establish itself as a legitimate source of diamond supply; however, faced with complex mining ecosystems and operating conditions that are vastly different from the large-scale diamond mining sector, De Beers says “the approach to supporting formalisation must be tailored, incremental and robust”. While the ASM sector represents an important source of global diamond production and is a critical livelihood, artisanal miners face many challenges, including a lack of capital, low productivity and informal practices, according to the diamond miner.
