An excellent rich example for the species, metallic bright lustrous needlelike crystals of owyheeite measuring to 0.4 cm in length are forming a cluster with pyrite and quartz. In great condition. The specimen comes with a previous label from the collection of Eric Laskowski.Located in Gaoming District, Foshan, Guangdong Province, China, the Fuwan Ag deposit forms a major portion of the Changkeng-Fuwan gold-silver district situated along the Yunkai Terrane margin. The mineralization is hosted within a complex sediment-hosted epithermal and structural system characterized by quartz-sulfide veins, breccias, and silicified alteration zones along fault boundaries. Extensive exploration, drilling, and feasibility evaluations were conducted primarily by Minco Silver Corporation starting in the mid-2000s, establishing the locality as a significant underground silver reserve. Among the dense assemblages of ore minerals, the deposit features owyheeite, a rare metallic silver lead antimony sulfosalt that occurs as fine metallic needles, acicular fibers, or massive intergrowths within the hydrothermal sulfide veins alongside minerals like galena, sphalerite, and pyrite.
