Calcite, Fluorite, Willemite, and Aragonite?; Hull Mine, Arizona

A really stunning piece from the Hull Mine, in Arizona. Red calcite, blue fluorite, green willemite, and potentially white aragonite--though the latter is not known for certain. Note, the willemite is nicely phosphorescent, while the alleged aragonite, is not. Shown in SW+LW, SW, LW, and natural both A-side and B-side.
