Lollingite is an iron arsenide mineral that forms in short prismatic to tabular crystals and a metallic to sub-metallic luster. It typically presents a gray to steel-gray color, sometimes with a slight bronze sheen on fresh surfaces, and can occur in granular masses or as elongated crystals associated with sulfide deposits. Commonly found in hydrothermal veins and skarn environments, lollingite often accompanies other arsenides and sulfides, reflecting its formation under relatively high-temperature geological conditions.

About Lollingite
Notable localities include China, Morocco, Austria, Germany, and Australia, where specimen quality ranges from dense, metallic crusts to well-formed crystals. Collectors value lollingite for its crisp crystal habit and the contrast between its dark metallic lustre and lighter matrix in composite specimens. While not as famous as some arsenides, well-prepared samples can display interesting surface sheen and epitaxial intergrowth with related minerals, making them a solid addition for those building arsenide or pyrite group collections.
