Crystals that are radioactive
WebAt this point the geodes were formed, but they were filled with rock crystal instead of amethyst. However, as these geodes remained buried, they were irradiated by the decay of radioactive minerals in the surrounding basalts. This radiation created color centers in the quartz, and that transformed the clear quartz into amethyst. http://www.galleries.com/minerals/property/radioact.htm
