Mounded group of zoned yellow fluorite with light purple rims and associated modified calcite crystals. There are also numerous chalcopyrite inclusions just within the fluorite surface. I am confident that the ascribed location is correct as based on the era of the collection, ie., (from the 1960s through ca. 1981) and employment with Ozark-Mahoning Company. Mined ca. 1970s from the great production days of the Bethel Horizon. In excellent condition. Wayne Fowler collection. Entered into Ross C. Lillie database as RCL2593.
