Artisanal miners extract emeralds by hand, making mining slow and sometimes sporadic. Still, the newspaper Addis Fortune reports that, as of August 2017, the export of 2,000 kg of emerald rough has generated about $7 million and employed around 30,000 people. (2017) Continuing exports of gems will aid in Ethiopia's already fast economic growth.
