Fluorite on Sphalerite with Pyrite, Calcite, Galena and Chalcopyrite

A classic old time Naica specimen with well crystalized Sphalerite serving as the host rock on which green modified octahedral Fluorites formed and on which Chalcopyrites are littered across their faces. Likely came out in the late 1970s and brought to market by Consie Prince. Ex Mike Wortham
