Fluorite, Minerva No. 1 Mine (Ozark-Mahoning No. 1 Mine), Ozark-Mahoning group, Cave-in-Rock, Hardin County, Illinois, USA
Size: 6.7x6.0x3.1cm
Species: Fluorite
Locality: Minerva No. 1 Mine (Ozark-Mahoning No. 1 Mine), Ozark-Mahoning group, Cave-in-Rock, Hardin County, Illinois, USA
Description: This intergrown cubic blue and purple fluorite looks killer when backlit and a lovely purple phantom becomes more clearly visible in the largest upper left cube. The left side of the specimen is primarily blue and the right side of the specimen is primarily purple. The specimen looks much better than my photo setup is able to show. The mine has been shut since 1996 and has little hope of ever being reopened due to cheaper mining costs associated with fluorspar deposits in other parts of the world notably China. A true American classic these minerals have become a staple of collections of any serious USA collector.
