This specimen consists of numerous veins of violet-colored stichtite, accompanied by veins of serpentine. Stichtite is a rare hydrated magnesium and chromium carbonate. The species is named after Robert Carl Sticht, the renowned American copper metallurgist and mine manager. At Kaapschehoop, stichtite occurs as irregular to rounded masses or as veinlets, generally less than 1 mm wide, within the serpentine.
