This is a "top drawer" specimen with incredible sprays of white (near center) to colorless Natrolite crystals in sprays to 9mm across. The individual crystals have nearly flat terminations with two low angled faces. The cross-sections are square. There are also waterclear chabazite(?), which are thin and tabular. Some of the Natrolite crystals pierce the Chabazite.  Incredible specimen. You will not be dissapointed with this zeolite specimen.
