Huaron Mine, Ancash Department, Peru
This small piece consists of a cluster of intergrown Sphalerites that actually makes up the base of the piece. The largest of these crystals reaches a diameter of 0.9" (2.3 cm), and is likely in the best condition, as the others are at least moderately damaged. They are all heavily intergrown, but they appear to have a good octahedral form, with well-defined edges and striated but clean faces. They have a bright pearly luster and a dark black-brown color, and are essentially opaque. The Sphalerites are accompanied by several small pyrite cubes, 5 of which are clustered together, and a few tiny quartz crystals.
