Ramdohrite is a rare mineral belonging to the lillianite group.

At the type locality, the Chocaya mine, Sud Chichas Province, Potosí, Bolivia, ramdohrite is found in a silver-tin vein in fine-grained quartz in a hydrothermal vein, associated with pyrite, stannite, andorite, jamesonite, sphalerite and quartz (HOM, AM 16.132).

At Bear Basin, Washington, USA, ramdohrite is associated with andorite (HOM).
