Diamond Mining Methods

The earliest form of marine mining entailed shore diving, where a swimmer would collect diamond bearing gravel from the shallow seabed. Today technology has evolved to specialised ships that mine for diamonds deep out at sea. These specialised ships use a powerful crawler that sucks gravel on the seabed up through flexible hoses/pipes.
