Heptasartorite is a very rare mineral [3] with formula Tl7Pb22As55S108. It belongs to sartorite homologous series. [2] It is related to other recently approved minerals of the series: enneasartorite and hendekasartorite. [4] [5] All three minerals come from a quarry in Lengenbach, Switzerland, which is famous of thallium minerals. [6] Chemically similar minerals include edenharterite and hutchinsonite. [7] [8]
