Sphalerite and Chalcopyrite from Joplin Field, USA

Sphalerite and Chalcopyrite from Joplin Field, Jasper County, Missouri, USA

Specimen piece of Sphalerite and Chalcopyrite from the Joplin mining field, Missouri.

The specimen is a large, solid piece of metallic minerals, weighing 191 grams.

The Joplin field is a large locale and unfortunately I do not have any further information on where this came from - it comes with two previous owners collectors labels and the label we provide.
