Denton Mine, Harris Creek Sub-District, Hardin County, Illinois, USA
This fluorite is from the Denton Mine, Illinois. This fluorite is blue with some purple edging and purple core, there are no sharp phantoms. The luster is mild and crystallization is complete, and it has colorless calcite crystal associations on the top of the fluorite. Really quite nice presentation.
