The name sphalerite is derived from a Greek word meaning "treacherous," an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore). The alternative names blende and zinc blende, from the German word meaning "blind," similarly allude to the fact that sphalerite does not yield lead.
