A mosaic of color carved by nature

A mosaic of color carved by nature.

This stunning fluorite from the legendary Minerva Mine is everything that has made the Cave-in-Rock District famous. Layer upon layer of razor-sharp cubic crystals create an intricate cityscape of glassy geometry, while rich royal purples melt into warm golden honey tones with every change in the light.

The complexity of this specimen is what keeps drawing me back. Every cube, every edge, every transparent window reveals another hidden detail. It’s the kind of piece you can study for years and still discover something new.

Collector-grade Illinois fluorite has become increasingly difficult to find, and specimens with this combination of aesthetics, color, and crystal architecture are always in demand.
