Fluorite with Calcite from Minerva No. 1 Mine, Cave-in-Rock, Illinois

Elevate your mineral collection with this stunning golden fluorite specimen, sourced from the legendary Minerva No. 1 Mine in Cave-in-Rock, Illinois—a world-renowned locality in the historic Illinois-Kentucky Fluorspar District. This classic piece showcases vibrant golden-yellow fluorite crystals, exhibiting the iconic cubic habit that fluorite collectors adore. Intertwined with the fluorite are delicate white calcite crystals, adding a beautiful contrast and a touch of natural elegance to this display-ready specimen.

Crafted by nature over millennia, this 95.4 x 74 x 35 mm (148g) specimen features well-formed fluorite crystals with a glass-like luster, capturing light in a way that highlights its warm, translucent tones. The calcite accents, though some are naturally incomplete, lend a rugged, authentic charm that reflects the raw beauty of its underground origins. Additionally, the fluorite displays minor natural chipping along some edges, a testament to its journey from the earth, enhancing its unique character rather than detracting from its appeal.

Condition: Collector-grade with natural imperfections (minor chipping on fluorite, incomplete calcite)
