- Small Cabinet, 6.5 x 5.0 x 4.5 cm
- Los Chispas Mine, Sonora, Mexico
- Ex. Dr. Miguel Romero
A superb cluster of fat, 3-dimensional, 360-degree stepahnite crystals perched up on matrix! Stephanite of this quality is more rare than any of the other major ilver species collectors covet from this locality, and this piece is aesthetic as well. 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).
