Dark violet fluorite cubes grew on a quartz coated matrix with galena crystals. The fluorite has a satin luster and shows some bruising of the corners and edges. There are some small sphalerite crystals on the matrix as well. This piece measures 17 cm wide by 9.0 cm tall and 12 cm front to back. An interesting piece from an old mine in the district. This piece is from the Hill-Ledford Mine, Cave-in-Rock, Illinois - Kentucky Fluorspar District, Hardin County, Illinois.
