I think that David, who writes the general mineral descriptions, will be quite interested in this specimen. It solely consists of an intergrown aggregate of Heulandite crystals with a curved, s-shaped form, pearly luster, and very strange green color. I have no idea what might cause such a color in Heulandite! It shows translucence around its edges and one small area of definite transparence on one prism face. The cluster has two tiny spots of damage, at least one of which must be where the specimen was attached to its host rock. This is by far the weirdest zeolite that I have seen yet.
