|Specimen #2 collected from the Glove Mine. A mass of tabular wulfenite crystals, ranging from green to greenish-orange to clear/colorless to dark gray (pseudomorphs) in color. Width of specimen ~4.5 cm.|
|Specimen #2 Clear tabs of wulfenite along with a single tab showing a tan and black color. That single tab may be zoned or simply showing a partial pseudomorphed crystal. Width of photomicrograph ~ 9 mm.|
|Photomicrograph, Specimen #2, showing clear to partially colored wulfenite crystals with a dark gray matrix of coronadite. Width ~1.6 cm.|
|Specimen #2 with clear square tabs of wulfenite, dark gray coronadite and a "glob" (center right) of an unknown mineral, Note the very tiny, beyond my camera capabilities, of "fairy dust" covering the specimen. Width ~ 1.9 cm.|
|Specimen #2. Clear wulfenite crystals W1, partially pseudomorphed coronadite after wulfenite, W2, and broken tab of wulfenite, W3, less clear than W1. Width ~1.2 cm.|
|The lead carbonate cerrusite, a precursor needed for the formation of wulfenite (from the Flux Mine in Arizona). The molybdenum in the wulfenite came from circulating waters during oxidation. Width ~3.3 cm.|
Both specimens came from one of my favorite rock and mineral shops, the Tucson Mineral and Gem World on South Kinney in the southwest part of the city. This is a "real" rock shop with lots of dust, flats of minerals, thumbnail drawers, less expensive specimens, and two very nice and talkative brothers who have been in business 50 years. They encourage exploring the shop and "give away" specimens to young rockhounds. It is worth a visit if you are in Tucson.
