You might not recognize this at first glance as a heulandite, first because it is a floater rather than being stuck on a matrix as it usually is, and second because it is colorless rather than the usual salmon color. But a heulandite it is, a fine one that looks like a stack of flat, triangular crystals that have been squeezed in the middle. Fine luster on the side faces, and pearly on the two ends.
