A rich nearly pure mass of small crystals of what once called Smaltite with several zones of earthy purplish Erythrite and a powdery pink mineral that seems to be Bieberite but is not analized. The specimen comes with an old Neree Boubee (Paris, France) label and one from the John Marshall collection. An old collection numbers and handwritten labels are also attached to the underside but are not visible on display. In very good condition with the many cubic Skutterudite crystals in stacks and aligned groups.
