An Illinois classic with a pedigree to match

An Illinois classic with a pedigree to match.

This vibrant, double-sided cluster of richly saturated purple fluorite cubes is accented by sparkling chalcopyrite, making it a specimen that rewards every angle. With exceptional aesthetics on both the front and back, it’s like having two display-worthy pieces in one. The glassy luster, deep violet color, and sharp cubic architecture showcase everything that has made the Rosiclare Level of the legendary Minerva No. 1 Mine one of the world’s most revered fluorite localities.

What elevates this piece even further is its outstanding provenance. Originally part of the St. Louis Academy of Science collection, it later passed through Ed Haid, Roy Hurlburt Minerals, and Great Northern Minerals, creating a documented history that is every bit as impressive as the specimen itself.

Provenance: • Rosiclare Level, Minerva No. 1 Mine, Cave-in-Rock, Hardin County, Illinois, USA • Ex St. Louis Academy of Science Collection • Via Ed Haid • Ex Roy Hurlburt Minerals • Ex Great Northern Minerals

A true collector’s specimen—beautiful, historic, and display-worthy from either side.
