This is a gorgeous blue cleaved fluorite octahedron collected from Hardin County, Illinois.
Miners used to cleave these octahedrons out of the high-grade fluorite in the mines. They were common in the 50's and 60's when the mines were operating in full swing, but are very hard to find acquire anymore.
Ex Wolfgang Vogt collection.
