Minerva No. 1 Mine, Illinois, Cave-in-Rock Sub-District, Hardin County, USA
This is a beautiful gemmy fluorite from Minerva No.1 mine. This specimen shows a series of phantoms. An almost colorless edge turns to gentle blue and then changes to a dark purple phantom before zoning to yellow. The darker yellow central color shows needle like chalcopyrite inclusions, which is a classic feature for this locality. This crystal is a complete floater. The main crystal has some scuffing near the top, but the rest of the crystals is free from damage. Excellent piece.
