The various Trap Rock quarries are well known for their superb Prehnite "casts" or epimorphs. The large majority of these casts form as Prehnite after Anhydrite, but some of them form as Prehnite after Glauberite, which is exceptionally difficult to find. Over the last few years, the Fanwood Quarry (Weldon Quarry) has produced some of the most magnificent Prehnite after Glauberite "casts" in the world. This specimen is a top quality piece of this material featuring several light green, lustrous crystallized Prehnite "casts" after rhombic shaped Glauberite. The piece is crystallized on all sides and only has only tiny point of contact at the base. You would be hard pressed to find finer quality Prehnite after Glauberite from any world locality. A superb display piece of this extremely rare phenomenon in the mineral world.
