Fluorite with Quartz, Galena and Calcite

A very dimensional specimen with crystals to 2cm heaped one upon the other on a quartz coated breccia. The color is similar to the deep purple Elmwood fluorites. The back is coated with tiny calcites.  A single 8mm galena is perched near the top back. You can spy it on the left side of the largest back crystal. A rare 4 species combination from this mining district. I really like this one. This piece came from the Chet Lemansky collection.

Locality: Rosiclare Mining District, Cave in Rock, Illinois

Composition: calcium fluoride
