Fluorite, Calcite & Pyrite

San Martín Mine
Zacatecas, Mexico
Epic Fluorite-Calcite-Pyrite combination specimen from the legendary San Martín Mine, in Zacatecas, Mexico! Gemmy purple fluorite cubes with beveled edges, sparkling white calcite rhombs, and brassy pyrite flakes create perfect contrast and balance on a single matrix. In this video, we take a detailed look at the chemistry, luster, hardness, and crystal systems and how these minerals formed in a hydrothermal-skarn system. A mind-blowing specimen with fluorescence from a historic silver-zinc-copper powerhouse.
