This jewel-like cluster features brilliantly clustrous, clear fluorites showing cuboctohedral crystals with dramatic an dcomplex modifications to their tips. They are perched on equally sparkling sulfide matrix of pyrite, making for a stark contrast that really just leaps out, despite not having the traditional pastel color hues most Naica fluorite has. The overall look of this subtly complex piece is just different, and more brilliantly lustrous, than most Naica specimens. Despite the good photos, it is even better in person. One of the special fluorites among many in this fine old Mexican mineral collection. Joe Budd photos.
