2.3 x 0.6 x 0.6 cm. Most collectors know natrolite from San Benito only as a snow-white microcrystalline setting for crystals of neptunite and benitoite, the stuff you have to clean off with acid to expose them. But here, you have a RARE, LARGE crystal of natrolite, complete and perfectly terminated - a fine specimen in and of itself! Crystallized natrolite from here is VERY uncommon.
