Fluorite -classic zoned Illinois

Illinois, United States
7.8 x 5.8 x 3.9 CM (cabinet)
A choice old Minerva mine specimen with strong purple to yellow zoning. In very fine condition and with wonderful details of stepping and complex face planes. The photos have a little backlight to show the color and zoning with stronger backlight they are far more dramatic, brighter and intense but not typical of a normal display. Without any backlighting the zoning is visible but subtle. A few tiny Chalcopyrites are evident too.
