A rare mineral containing copper and tungsten in oxide form, found in oxidized zones of certain metal ore deposits.
From Latin 'cuprum' (copper) combined with 'tungsten' and the mineral suffix '-ite', indicating a mineral containing both elements.
Tungsten minerals are so heavy and dense that a small piece feels surprisingly heavy in your hand—add copper to the mix and you get cuprotungstite, a collector's piece that feels like holding a secret from Earth.
