Sunset fire in a cube

This Cave-in-Rock fluorite is an absolute stunner—glowing golden-yellow cores wrapped in vivid violet and soft pink zoning, all locked into razor-sharp, ultra-lustrous cubes. The color layering is insane… warm to cool tones colliding in a way only Illinois fluorite can deliver.

That signature Cave-in-Rock look is on full display here—glassy faces, crisp geometry, and zoning that shifts and intensifies with every change in light. It’s bright, electric, and impossible to ignore.

Pieces with this level of saturation, contrast, and luster are what made this district legendary—and why collectors still chase them hard today.

For the fluorite lovers… this is pure heat.
