Organic Popcorn Glass Gem (Net Weight 8g.) Matures in 60 days. Unwrapping a husk of Glass Gem is like looking at a beautiful stained glass window, with all the translucent colors of a rainbow. Developed by Carl Barnes, a part-Cherokee farm breeder from Oklahoma. Many years of selecting the most vivid translucent kernels went into this beautiful popcorn. Not just an ornamental but also good for popping or grinding into cornmeal.
