Ex. Dr. Miguel Romero
A superb, freestanding acanthite cluster with high luster and incredibly fine crystallization. This was regarded as the #2 or #3 acanthite in the collection, depending on personal tastes, only because Romero also had the famous larger specimen shown elsewhere in this update. For anybody else, it would have been their unsurmountable, #1 piece. And in any case, this specimen exhibits more textbook form, for the species, in an unusually elegant cluster. It is, by any standard, a killer for the species and locale, of the highest level. 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, and has since been featured in the book "The Miguel Romero Collection of Mexico Minerals" which we sponsored as a special supplement book (published by the Mineralogical Record in December of 2008).
