The Braen's Quarry in New Jersey has been a seldom collection quarry for year, but has been a source of excellent Zeolite specimens and associated species. This piece features no Zeolites, but it hosts lovely golden Calcite scalenohedra which are wedged in the middle of a superb quality cast of Quartz after Anhydrite. The cast is especially nice because of the Anhydrite grew in several different directions, creating a wonderful three-dimensional effect. You can see the delicate, thin, bladed, cavities where the Anhdyrite once existed and dissolved away after the Quartz formed around them. A wonderful example of this fantastic phenomenon in the mineral world. Ex. Richard Kosnar Collection.
