In 1999, a geophysicist named Russell Seitz walked into a jade shop in the colonial town of Antigua, Guatemala, and noticed a hand-sized sample of rare blue jadeite sitting on a shelf. That stone would lead him into the mountains of the Sierra de las Minas, where he and a prospector named Carlos Gonzales Ramirez found jade boulders the size of a bus and veins of jadeite two meters wide stretching forty-five meters through the rock -- deposits that had been worked for thousands of years by the Olmec and Maya, then lost to history when the Spanish, interested only in gold, ignored the green and blue stones entirely. The Sierra de las Minas -- the "Mountain Range of the Mines" -- earned its name from centuries of small-scale jade and marble extraction. What no one realized until the end of the twentieth century was just how much remained hidden inside.
