Pyrargyrite from Mexico, Zacatecas, Fresnillo Municipality, Fresnillo

Pyrargyrite is a rare mineral composed of silver, antimony, and sulfur. This specimen features a stunning composition of rhombus shaped calcite on it. It displays beautifully from any angle, with the front and the back having completely different photogenic personalities. I was lucky enough to pick up this specimen at the 2026 Tucson show. It is a truly special piece to me.
