Minerva No. 1 Mine, Cave-in-Rock Sub-District, Hardin County, Illinois, USA
An exquisite, well crystallized, richly tri-colored fluorite showing blue to purple to yellow, with chalcopyrite inclusions. The luster of the finely-stepped faces is very good, and the overall aesthetics are excellent. Brassy crystals of chalcopyrite are embedded on and within the fluorite creating the famous “speckled” look and add detail to the piece. A classic and beautiful, fluorite crystal from the Minerva #1 Mine of Illinois.
