Illinois fluorite doesn’t get much better than this.

Two deeply saturated violet fluorite cubes perched perfectly on a sparkling bed of jet-black sphalerite—an iconic combination from the legendary Denton Mine that defines why Southern Illinois remains one of the most revered fluorite districts on Earth.

The contrast is extraordinary. Sharp cubic geometry rising above a sea of mirror-like sphalerite crystals. Rich grape-purple color. Incredible aesthetics from every angle. This is the kind of specimen that stops collectors in their tracks.

What makes it even more special is its provenance.

This specimen comes from the celebrated Ross Lillie Collection, a name synonymous with the finest Illinois fluorites ever assembled. Ross spent decades acquiring many of the district’s most important pieces, and specimens bearing his provenance are increasingly sought after by serious collectors worldwide.

One of the best.

A true trophy piece combining world-class aesthetics, a legendary locality, and elite collector pedigree.
