Size: 5 x 3 x 4 inches. Here is a stunning fluorite specimen with wisps of ghostly color imbedded deep in the translucent crystals. It is from the Minerva # 1 Mine in Hardin County, Illinois. The color ranges from clear to blue to purple to yellow, all mixed up in a rainbow of beauty. Best if displayed in a well lit cabinet or sunny area to bring out the color. The crystal faces are surprisingly smooth for for Illinois fluorite. The condition is excellent.
