A lovely example of the crystalline Azurite that comes from this locality, this specimen boasts at least 10 monoclinic tabular crystals. Though several show substantial amounts of breakage, there are many that are intact and have clean, smooth faces and well-defined edges that show off a bright, vitreous luster. All have a navy-blue color that is so deep as to render the crystals opaque, except under extremely bright light. These crystals do not exceed 0.3" (8 mm) in any dimension and are sandwiched in a large quantity of a pale blue, powdery substance that I can only guess is a decomposition product of either Azurite or some other copper mineral. This material has a very odd form that I have not seen before- it shows definite, individual layers in some areas. They are extremely thin and are spaced slightly apart from each other. There are several smaller pockets of this material scattered in the brown hAZU-31
