Romero particularly prized these datolites, which before the discovery of (somewhat different styled) crystals from Dalnegorsk, were surely the worlds best of species. Even still today, they have amazing symmetry and geometry that are not often equaled. He had 3 in the collection. This is the largest of them, the only cabinet sized specimen. It is a complete mound of geometric, translucent, seafoam-green crystals of datolite, measuring to about 2 inches across. For crystallography, these old datolites really are highly desirable, but so seldom seen. In great condition, and with a nice accent of pyrite! An elegant example of this species, from a locale that most folks simple have never seen one from. This specimen from the Dr Miguel Romero collection was on loan exhibition to the University of Arizona Museum for over a decade, until my purchase of this collection in 2008. It was on display in special cases at the museum. Comes with custom lucite base already made for the specimen.
