A nice branching cluster of prismatic but hollow arms that show the original form of the Glauberite very well. A choice thumbnail from a classic USA locality that is in excellent condition. While good cabinet specimens were known from both the Houdaille and McDowells Quarries here, thumbnails seem to be very rare. This has a good reddish color as well, looks fine from all sides. These are often labeled as pseudomorphs but should more correctly be called Epimorphs as the orginial Glauberite is not replaced but is completely gone.
