location:
Davis-Deardorff Mine, Hardin Co., Illinois, USA
description: The Davis Deardorff Mine in Hardin County, Illinois was one of the notable mines in the Illinois Kentucky Fluorspar District near Cave in Rock. The mine worked fluorite deposits that occurred as veins and replacement bodies in limestone. Production included fluorite along with associated minerals such as calcite, galena, and sphalerite. The mine operated during the 20th century and contributed to the regions role as a major supplier of fluorspar for the steel and chemical industries.
A deep rosy purple color zoned semi lustrous translucent grouping of cubic fluorite crystals. Minor quartz and sphalerite are present. Beautiful when backlit. Some damage present as seen, this still very nice.
