Barite w/ Marcasite and Calcite

Linwood Mine, Buffalo,

Scott Co., Iowa

USA

4x2x3.5cm

Exceptional barite specimen featuring lustrous white barite crystals intergrown with brassy marcasite and translucent calcite. This classic Iowa locality piece showcases the mineral diversity characteristic of the Linwood Mine in Scott County—a historically significant source for collector-grade specimens. The specimen measures 4 × 2 × 3.5 cm, making it an ideal size for display or study. The contrast between the pearlescent barite, metallic marcasite, and glassy calcite creates striking visual interest under natural and directed light. A fine addition to mineral collections focused on Midwestern American localities or classic sulfide and carbonate associations.
