From what I can gather (even the Discover article isn't particularly deep) this is a natural mutation and not a man-made one?
As far as I understand it is a natural variety.

Like many heirloom treasures, Glass Gem corn has a name, a place, and a story. Its origin traces back to Carl Barnes, a part-Cherokee farmer living in Oklahoma. Barnes had an uncanny knack for corn breeding. More specifically, he excelled at selecting and saving seed from those cobs that exhibited vivid, translucent colors. Exactly how long Barnes worked on Glass Gem—how many successive seasons he carefully chose, saved, and replanted these special seeds—is unknown. But after many years, his painstaking efforts created a wondrous corn cultivar that has now captivated thousands of people around the world.
Approaching the end of his life, Barnes bestowed his precious seed collection to Greg Schoen, his corn-breeding protégé. The weighty responsibility of protecting these seeds was not lost on Schoen. While in the process of moving in 2010, he sought out a place to store a sampling of the collection to ensure its safekeeping. Schoen passed on several unique corn varieties to fellow seedsman Bill McDorman, who was owner at the time of Seeds Trust, a small family seed company then located in central Arizona. (Today, Bill McDorman is Executive Director of Native Seeds/SEARCH.) Curious about the oddly named Glass Gems, he planted a handful of seeds in his garden. The spectacular plants that emerged took him by surprise. “I was blown away,” McDorman recalls. “No one had ever seen corn like this before.”
The story of Barnes, Schoen, and their remarkable corn is not unusual. For millennia, people have elegantly interacted with the plants that sustain them through careful selection and seed saving. This process, repeated year after year, changes and adapts the plants to take on any number of desirable characteristics, from enhanced color and flavor to disease resistance and hardiness.
The bounty of genetic diversity our ancestral farmers and gardeners created in this way was shared and handed down across generations. But under today’s industrial agricultural paradigm of monocropping, GMOs, and hybrid seeds, this incredible diversity has been narrowed to a shred of its former abundance. A 1983 study compared the seed varieties found in the USDA seed bank at the time with those available in commercial seed catalogs in 1903. The results were striking. Of the 408 different tomato varieties on the market at the turn of the century, less than 80 were present in the USDA collection. Similarly, lettuces that once flourished with 497 heirloom varieties were only represented by 36 varieties. The same held true for most other veggies including sweet corn, of which only a dozen cultivars were preserved out of 307 unique varieties once available in the catalogs. Though this data leaves some questions around actual diversity decline, the trend toward dwindling crop diversity is alarming. In just a few generations, both the time-honored knowledge of seed saving and many irreplaceable seeds are in danger of disappearing.
