A miner rests at the entrance of a tunnel in the Coscuez mine in the emerald mining region, some 100 miles north of Bogota, Aug. 26, 2002. The work is strenuous in the deep in tunnels where the miners gouge the earth looking for the gems. Despite a drop in emerald production in Colombia, "green fever" still burns among miners who yearn to find a stone big or pure enough to answer all their worldy needs. (AP Photo/Ricardo Mazalan)
