On a basaltic matrix along with dark gray chalcedony, is perched one of the better heulandite fans, I have seen. The glassy luster, translucence, and pastel salmon color, are exquisite, especially in contrast to the dark matrix. The fan measures 7.0 cm across. In addition, there is a 1.5 cm pearlescent, doubly terminated stilbite crystal on the heulandite. Wow!
