Celestine with Calcite

specimen number:
2212148

location:
Stoneco Quarry, Lime City, Wood Co., Ohio, USA

description:
Sparkling light blue crystals of Celestine to 1.0 cm in size on a brecciated limestone matrix with minor calcite. In good condition with just slight micro-damage present.

The Stoneco Lime City Quarry, located in Lime City, Wood County, Ohio, is a prominent industrial operation famous among mineralogists for producing exceptional specimens of celestine (celestite). Geologically, the quarry is situated within the Lockport Dolomite, a Silurian-age sedimentary formation consisting of magnesium-rich limestone that contains numerous solution cavities, vugs, and fractures. Within these open spaces, late-stage, strontium-rich hydrothermal fluids precipitated magnificent, well-formed crystals of celestine, which typically occur as transparent to translucent, pale blue or colorless tabular prisms, often associated with calcite and fluorite. Historically, quarrying for crushed stone, lime production, and construction aggregates began at the site in the late 19th century and has continued systematically through various corporate owners into 2026. While the primary economic focus of the quarry remains the extraction of limestone on an industrial scale, the periodic discovery of mineral-lined vugs during blasting operations has made it a classic North American locality for collectors seeking high-quality celestine specimens.
