Perched on a sliver of sphalerite and a smaller crystal of datolite is a superb, well formed, translucent, seafoam-green crystal of datolite, measuring 4.5 cm across. Alternating faces of matte luster and glassy luster add to the sharp form of this specimen. For crystallography, these old datolites really are highly desirable, but so seldom seen. Romero had 3 of the best I know of, this and another being well-balanced in their size range, with sharp crystal habit and excellent aesthetics compared to the usual jumbly plates which came out (perhaps 20 years or more ago). An elegant example of this species, from a locale that most folks simple have never seen one from. Comes with custom lucite base already made for the specimen.
