Dingdaohengite-(Ce) is a rare mineral belonging to the perrierite group, typically occurring in complex carbonatite-hosted environments. It is characterized by its dark, often tabular crystals and submetallic luster. It is primarily sought after by advanced systematic mineral collectors due to its restricted occurrence at the Bayan Obo deposit.

Field-hunting tip
Look in hydrothermal veins in carbonatite deposits country — that is the host setting where dingdaohengite-(ce) typically forms. If you start seeing aegirine, baryte, fluorite in float, you are in the right ground. Field specimens usually show a tabular crystals habit, so train your eye for that shape before scanning the outcrop.
