A beautiful group of rich yellow fluorite with bluish purple rims liberally scattered with high luster calcite scalenohedrons. Fluorite crystals to 5.5+ cm. Years ago I sold this specimen to Dr. London at TGMS 1995. It was a difficult decision as I wished to keep it in my personal collection. In top condition and displays well from a variety of angles. Mined 1994 from "government royalty ore".
