The Braen Quarry in New Jersey has been a seldom collected quarry for years, but has been a source of excellent Zeolite specimens and associated species. This piece features no Zeolites, but is filled with sculptural, sharp, blocky, striated, hollow "casts" of Datolite after Anhdyrite. There are some sharp, gemmy Datolite crystals on one side of specimen as well, giving the piece a lot of character. A wonderful example of this classic Trap Rock material. Ex. Richard Kosnar Collection.
