ILLINOIS FLUORITE AT ITS FINEST.

Some specimens simply check every box… and then there are pieces like this.

This collector-grade fluorite from the legendary Minerva No. 1 Mine in Cave-in-Rock, Illinois delivers everything serious collectors chase: razor-sharp cubic form, mesmerizing blue-to-violet color, incredible internal zoning, and that unmistakable electric glow that comes alive as the light moves across the crystal. Every angle reveals another layer of depth, making it impossible to stop turning in your hands.

Mounted on a handcrafted Sunnywood custom base, this is the kind of display piece that immediately commands attention in any fine mineral collection.

Absolute banger. Collector quality through and through.
