Moctezuma Mine, Sonora, Mexico
Small Cabinet, 5.8 x 3.0 x 1.6 cm
Ex. University of Arizona
A beautiful, lustrous specimen of stibarsen, normally not one of your sexier metallic species. The piece is convex on one side, concave on the other, and presents nicely either way. This mineral is composed of simply AsSb - arsenic and antimony, with no other elements. It is a very weird thing, thus! From the collection of the University of Arizona Museum. Joe Budd photos
