Wow - this may be the most facinating specimen we have ever sold.  As you can see it is a delicate network of Aragonite crystals to 1cm. In fact, the entire specimen may indeed be Calcite. Looking closely at this specimen, the terminations on each side are profoundly different. The base crystals are clearly rhombic with one blunt, equant crystal forming the termination. The opposite, pointed end, that looks like the Denver airport, are composed of thin, discoidal crystals stacked in a fashion that produced a sharp single column which apparently grew out of several converging columns. It's one weird crystal formation, which I haven't a clue as to how it formed. It seems to be a floater as there are no attachment points so possibly it formed in a clay. It will require insurance and careful packing which we are capable of.
