3.6" Rhodochrosite Stalactite Slice with Galena Inclusions - Argentina

This is a polished rhodochrosite stalactite slice containing galena, collected from the Capillitas Mine in Argentina. The portion of this mine that produced these types of banded rhodochrosite specimens, was mined out decades ago. The banding of this specimen is beautifully defined and contains wonderful coloring.
