A gorgeous plate of colorful, glassy, lustrous fluorite crystals measuring 12.5 cm tall from the Minerva #1 Mine, Cave-in-Rock, Hardin County, Illinois USA. The Minerva #1 mine, considered by most collectors to be the preeminent specimen producer in the Southern Illinois Fluorspar District, is noted for these highly-colorful, visually-complex fluorite specimens featuring a combination of colors and different successive fluorite crystal generations that few other localities worldwide can match. This specimen has been visually attributed to the Adams-Clancey Drift area, which produced a number of superb specimens of this distinctive style around 1994-95′, shortly before the mined closed forever.
