Adamites in general are pretty terrific, but the holy grail of the species is definitely the purple varietal, which are so very rare. These were found just once, around 1984 if I recall. This incredible crystal is gemmy, has fine color, and has three perfect crystal faces as well as the termination. If you look carefully at the pics, you will notice that what seems like fuzziness is really some unbelievable double refraction within this gemmy crystal. Super large crystal! 3 x 1.5 x 1 cm
