A variety of Diopside
A variety (diopside-hedenbergite-augite solid-solution member of the pyroxene group) specifically showing prominent {001} parting and originally supposed to be a distinct species. Occasional misidentifications included orthopyroxene, e.g Metalloidal Diallage = Hypersthene and Talkartiger Diallage = Diaclasite.
