A cluster of globular growths.Crystals are lenticular rhombohedrons and they have its dark color due to the inclusion of fibrous boulangerite (or jamesonite! both are present in this mine, and in the same places!) completely filling their interior.Between some crystals,we can see free boulangerite microcrystals.Calcite crystals show a good "velvet" luster and sharp terminations.
Pleasant shape, in very good condition.
