Fluorite, Minerva No. 1 Mine, Cave-In-Rock, Hardin County, Illinois

Unknown Owner

A lovely deep purple to “blurple” fluorite specimen from the classic and historic Minerva No. 1 Mine. The internal blue “phantoms” are overgrown by purple growth zones, and scattered sulfides on or just below the crystal faces add a bit of contrast and sparkle.
