Rosiclare, Illinois

Sunday, 30 September 2012 01:00 PM

Mining at the world's largest Fluorspar deposit near Rosiclare in southern Illinois has produced some of the most colorful minerals ever seen. Mining has long terminated, but we have managed to assemble a small lot of fantastic examples from this district, most of which are from the Don Phillips collection.
