This rather simple, small hand specimen consists of an amorphous chunk of Zinkenite, a rather complex lead and antimony sulfide. The material appears to be a piece of a larger chunk, as only a small portion of its surface is not fresly broken. The fresh areas show a dark gray coloration and a bright metallic luster, and are punctuated by thin crusts and veins of white crystalline calcite that extend through parts of the material. There is no host rock present, however.
