This fancy crystal measures 2.3 cm on longest edge and is perfect all around, hanging off a bit of matrix and so exposed more than usual for a cubic crystal on matrix. It is subtly phantomed with purple cores in green outer layers. The crystal, along with an associated quartz, is perched in muscovite matrix which forms a nice natural knoll. It is complete all around Minute chalcopyrite (?) inclusions add a nice accent when studied close up!
