Mineral: Löllingite and Arsenopyrite on Dolomite and Calcite with minor Magnetite
Locality: Hexigten Banner (Kčshíkčténg Qí), Chifeng (Ulanhad), Inner Mongolia Autonomous Region, China
Dimensions: 11 x 14.5 x 9 cm / main crystal: 6.5 cm.

Description: Mass: 598 g MIM number: 1339 Probable year of extraction : 2012 Curved polycrystalline growth of gray lollingite, complete including at the back, sprinkled with small, lustrous, silvery pseudo-octahedral crystals of arsenopyrite. It is studded on a white 9 cm wide rhombohedron of white dolomite, itself resting on a matrix of white calcite strips. A small magnetite crystal is on the back of the lollingite, at its base.
