An ULTRA-RARE, unusual and SUPERB specimen of a radial bundle of brassy millerite needles embedded in and on a PRISTINE, transparent, light gray calcite rhomb from the famous quarries around Keokuk, Iowa. I have never seen a millerite specimen of this quality and association. Ex. George Feist Collection.
