A large and bold inclusion gem. Colorless Quartz with a single large platelet of green Mica (usually classified as Annite at this locale, though Biotite is also possible). What makes these so intriguing is that the included Mica is so thin that it is capable of being transparent in normal transmitted lighting despite its bright green bodycolor.
