FOV=1.8 cm. Detail showing variety of crystal habit and color zoning in wulfenite from the Helena Mine, Slovenia. On other portions of the specimen, the wulfenite is a bright orange-peach color. Originally it was disfigured by clots and granules of calcite (see last photo in series), but these were removed with vinegar, which greatly improved the luster of the wulfenite. Two stereo views in this series. Collection and photo, T. Peterson.
