This is one of the largest crystals of the species, so far as I know. I have never personally seen one so elongated and complete. Not only is it big, it is miraculously pristine - which if you have seen a number of these, you know how rare that fact is. The large crystals spray up vertically from a thin shard of matrix at the base. Overall, this is extremely aesthetic AND important, for the species. It is not the typical example, by any means, and I was enormously impressed when I first saw this in a collection nearly a decade ago.
