A silver sulfide mineral (Ag₂S) that is an important ore of silver, appearing as dark gray or black crystals.
From Greek 'argyros' (silver) combined with the mineralogical suffix '-ite' (mineral or rock), literally meaning 'silver-containing mineral.'
Argyrite is how miners find silver—this dark mineral is essentially concentrated silver waiting to be extracted, and its name literally says 'silver-stone,' making it a chemical clue written in Greek for geologists.
