The Knight Mine is in the Rosiclare District and as such is a vein-type ore body. Note the clear and lavender color of the fluorite and parallel growth of waxy luster crystal as characteristic of vein-type fluorspar. Also, the combination with white calcite scalenohedra is classic from the district. in excellent condition. Dr. Perry & Anne Bynum Collection. Mined c. mid-late 1970s.
