Wulfenite from Mexico, Chihuahua, Ahumada Mine

An unusual looking specimen of orange Wulfenite crystals with Arsenatian Vanadinite that measures 5 x 5 cm. The specimen came with an old label from Bentley's Minerals and a stamp-over of "Neal Yedlin Coll," labeled simply as "Wulfenite, Ahumada, Chihuahua, Mexico". Christopher Wentzell noted: "I have never seen another Wulfenite like this from the locality, so it perked my interest. My initial thoughts were that it was either really bad, or (because of the provenance) perhaps very good. Peter Megaw kindly took notice and advised me the following about it: "This is not an uncommon association with the vanadinite coating the wulfenite, but this has the wulfenite exceptionally well exposed, which is unusual..."
