How do you extract rubies from rocks?
In the pit mining technique, workers use a large metal tube to bring up a core of gem-bearing gravel. They typically extract a core from three to twenty-four meters deep. Because the rubies are extremely hard, the mother-rock is then eroded away from around them and, thus freed, they wash downstream.
