Description:From the great find of 2004. This specimen is a very attractive, incredibly rare, superb quality, crystallized specimen of the extremely rare variety of Franckeite, Potosiite hosting of lustrous, heavily striated, tabular blades measuring up to 4 mm (!) sitting atop crystallized Franckeite on matrix. For those of you who are unaware, the crystals of Potosiite on this specimen are rather large. Before these new specimens were discovered, some of the largest known crystals of Potosiite were massive, uncrystallized, granules less than 1 mm. in most cases. The crystals on this specimen are NOT micros, you can clearly see them with the naked eye.
