Kelly Mine, Magdalena District, Socorro Co., New Mexico, USA
Ex. A. E. Seaman Museum
At first glance, this looks like Smithsonite for which the Kelly mine is noted. However, a drop of acid produced instant fizzying action. The surface has a glossy luster and distinct banding can be seen in the sides. In person, there is just a hint of a greenish color preesent.
Condition: Very Good
Flaws: Nothing Appreciable
