New New Jersey finds are always exciting, and this discovery last year of a pocket of super-sharp, gorgeous green pseudomorphs of prehnite after glauberite was a real treat! We bought many of the available specimens from this pocket, all that were at the show back then. This was the largest specimen in this update, with crystals to 3 cm. Some of these crystal casts are open on the front, so you can see their hollow structure. What we describe here as prehnite "crystals," for the sake of simplicity, are actually hollow prehnite casts of the original glauberite crystals, with the beautiful mint-green prehnite (very difficult to photograph and prettier in person) perfectly retaining the form of the glauberite crystals! Though prehnite pseudomorphs have been found in New Jersey before, these new ones are exceptional for their exquisite form and bright color. 6.5 x 6.5 x 4.5 cm
