An exceptional exmaple of this classic pseudomorph! Prehnite from the trap rocks of New Jersey is both famous and beautiful. The lustrous, translucent, light apple green color is lovely; but when you add the fact that it has pseudomorphed anhydrite, and retained such good sharp form, this becomes major. The large crystal measures all of 8 cm in length. It is extremely 3-dimensional, and complete all around.One of the finer examples I have seen for sale of this classic material!
