Description
Very nice classic combination from the Sabinas Mine in the state of Zacatecas, Mexico. Cuboctahedral purple Fluorites crystals up to almost 1.5 cm are translucent and highly lustrous. They are associated with beige-colored Calcite scalenohedrons, clusters of small tombak-colored Pyrrhotite crystals, and brass-colored, iridescent Chalcopyrite crystals. A lot to look at, better to do that in person.
