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]
