This obscure metal is exceptionally difficult to separate and refine from its ores and equally difficult to keep it from oxidizing right back into an "ore". It is the most reactive of the rare earth metals and will lose its luster within hours of being exposed to air. Obsessively clean labware is necessary to keep all traces of O2 from spoiling its surface with oxides and must be housed under argon gas to keep it that way. Not surrisingly, this is an expensive acquisition.
