From the collection of Robert Drift. This Trap Rock locality is one of the most impressive (and under appreciated) zeolite localities in the world. This quarry has produced some amazing specimens in the last 100 years. This particular specimen is a striking pseudomorph of hollow, sea-foam-green prehnite after a sharp, large, upright, 4.0 cm, tabular laumontite crystal on prehnite matrix. This is a very showy, complete-all-around and pristine pseudomorph specimen of solid prehnite from this historic New Jersey quarry.
