A large, 3-dimensional, robust crystal of this very complex rare earth element containing specie, s with niobium and tantalum in addition to uranium and other oddities mixed in. This is an older specimen, undoubtedly. Al obtained it in 1967 and it is labeled "Setesdal" although we canot find a reference to this locality. It may instead be from a nearby and known location, as Setesdal seems to be a valley district and not a specific mine name. In any case, an exceptional display-quality example of the species.
