Acanthite Wikipedia

Acanthite is a form of silver sulfide with the chemical formula Ag 2 S. It crystallizes in the monoclinic system and is the stable form of silver sulfide below 173 °C (343 °F). Argentite is the stable form above that temperature. As argentite cools below that temperature its cubic form is distorted to the monoclinic form of acanthite.
