Strongly tenebrescent sodalite (var hackmanite). The sodalite becomes a deep purple color after irradiation with longwave and, more strongly, shortwave UV light. Exposure to white light clears the purple color, and the sodalite returns clear (white). Strong orange fluorescence under longwave UV light, weaker under shortwave.
