A complex small specimen with two main large Bismuthinite crystals that are covered with tiny crystals of Stannite and Marcasite. The specimen also has areas of Chalcopyrite as well as some tiny needle crystals of Bismuthinite that seems to be a later generation. A choice example of the thicker type of Bismuthinite crystals and a nice association of these two Sulfides. From a recent find that was premiered in Munich in October 2019.
A attractive miniature with a prominent Fluorite cube that is densely filled with needles, hairs and curls of metallic Bismuthinite. Since the Fluorite rests on a well-crystallized cluster of Arsenopyrite, the overall contrast and esthetic structure is excellent. As with many fine Yaogangxian specimens, there are many associated species, this has Sphalerite, Stannite and Quartz. Better in person, this is an older specimen from the Shields Flynn collection.
