Fine, sharp silver Carrollite crystals are set on contrasting matrix in an esthetic arrangement. The crystals show complex modifications and growth patterns. Some micro crystals of what looks like Vesigneite are also present. Green copper staining and secondary minerals adds additional contrast. In very good condition which is remarkable for such a delicate mineral. Far better than average.
