From a late 2011 find, at this inactive old mine, these are just incredible crystals for the species! They are large, and have incredible luster to them. The piece looks more like a scolecite from India, because of the size and brightness, and it is hard to relate to other generally small and dull-luster examples of this species I have seen from other localities. A very surprising find, for rarities that appeared at the Tucson 2012 show. This was one of the larger specimens with good crystals. Note it has pockets sticking out all around.
