· Alluvial mining for diamonds is similar to alluvial mining for gold in that it essentially involves separating diamonds from sediment. At industrial operations, that is accomplished in various ways. For instance, when diamond-bearing sediment is found on the ocean shore or in river beds, it is removed and taken to a plant where it is washed
