This is a sharp, lustrous partial crystal of wodginite. In excellent condition, a couple of small chips. The exposed crystal faces are as bright and well-defined as any from this find – so sharp!
About These Wodginites
Wodginite is not a common mineral, and it is quite difficult to acquire good crystals. These ones are from a recent find that produced a small number of specimens. Their idetification has been confirmed at the University of Arizona, and, along with subsequent EDS work, it has been established that of the various members of the wodginite group, they are wodginite.
