A superb, arborescent cluster of lustrous and sharp pyrargyrite crystals are here perched on CRYSTALLIZED quartz matrix! THis is an extraordinarily rare occurrence, and a fine specimen from any locality. But for Taxco, where such large matrix pieces are rare, it is even of more import.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).
