Calcite var Manganoan on Galena

First, off, I must tell you that IF I was collecting anything outside of Tsumeb I would keep this piece. a matrix of chalcopyrite and galena give way to mirror bright cubic galena surrounding 2-3cm wheatsheaf shaped soft pink manganoan calcites. I have not seen a similar quality Naica piece of this combination. Very strong fluorescence up to the brush-like terminations where the manganese likely depleted. There is no damage to mention. This is a heavy pieces, so keep that in mind for shipping.

Locality: Naica, Chihuahua Mexico

Composition: Calcium carbonate with lead sulfide
