Description

A beautiful set featuring a superb calcite crystal, perfectly automorphic, brilliant and translucent, associated with golden pyrite crystals, sometimes mamelonned, crystals that overlapped tetrahedral-shaped crystals (probably galena).

Specimen from the Southeast Missouri Lead District, southeast Missouri, USA (United States). Maybe from the Joplin mine…

A specimen from the Hubin collection in Neupré, Belgium, delivered with its label.

Here is a video of this calcite crystal with pyrite from the USA :
