Smithsonite psuedo Calcite

San Antonio Mine,

East Camp, Santa Eulalia,

Chihuahua, Mexico

14x4x8cm

Smithsonite pseudomorph after calcite from the legendary San Antonio Mine in Santa Eulalia, Chihuahua, Mexico. This striking specimen showcases the classic replacement textures that make pseudomorphs so prized by collectors—where zinc carbonate has gradually replaced the original calcite crystal structure, preserving its geometric form while transforming its mineral identity. The specimen measures 14 × 4 × 8 cm and displays the characteristic pale blue-green coloration typical of quality Mexican smithsonite. The surface exhibits well-defined crystal faces and the subtle dimensional variations that reveal the pseudomorphic process. A compelling example of Mexico's rich mineralogical heritage and the dynamic processes that create collector-grade specimens. Ideal for display collections, educational study, or as a centerpiece for serious mineral enthusiasts.
