A large and old matrix specimen from the classic New Jersey locality. Present are gypsum cleavages plus a complete crystal buried in a protective cavity (fourth picture) as well as a band of mostly massive, purple amethyst quartz. The main interests here are the historical provenance (read this Mineralogical Record editorial on the sale of the Academy of Natural Sciences of Philadelphia mineral collection sale) and the association/locality.
