A stunning example of mineral paragenesis from America's premier fluorite district. This 136g specimen features a captivating cluster of translucent Calcite crystals elegantly perched atop a cubic Fluorite base. We curated this piece for the sharp contrast between the geometric rigidity of the fluorite and the delicate, elongated form of the calcite overgrowths. Sourced from the storied Cave-in-Rock sub-district of Hardin County, this specimen is a time capsule of the region's rich mining heritage. Its balanced composition and pristine crystalline faces make it a quintessential addition for collectors of high-contrast Illinois minerals.
