Illinois blurple at its absolute peak

Illinois blurple at its absolute peak

Next-level fluorite from the Hill-Ledford Mine, Cave-in-Rock—showing off insanely saturated zoning that shifts from icy blue edges into deep, electric violet cores. The translucency on this one is wild… like stained glass carved into razor-sharp cubes.

Layered growth, phantom zoning, and those inky inclusions give it serious depth—every angle hits different. Classic Illinois character, but turned all the way up.

This is the kind of saturation and structure collectors hunt for… and rarely find like this.

Pure Cave-in-Rock fire.
