What is alluvial diamond mining?

Alluvial diamond mining is the term used to describe the process through which diamonds arerecovered from such deposits of sand, gravel and clay.Large concentrations of alluvial diamond deposits are mined on an industrial basis. However,most alluvial diamond deposits are spread across huge geographic areas which cannot be easily isolated and therefore are not mined industrially. These deposits are mined informally, in a non regulated way. This is (commonly), known as artisanal or small scale-alluvial diamond digging.

Around 10% of the world’s rough diamonds are sourced through industrial alluvial mining and 14% through artisanal or small-scale informal alluvial diamond digging.
