Ojuela produced, rarely, beautiful blue scorodites of substantial appeal. This is a large plate for the location, with dozens of sharp crystals to 4mm. Even though scorodite from the other Mexican location is more famous perhaps, these are jsut as treasured by collectors...and hard to obtain today. 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) .
