Outstanding form and patina with excellent iridescent hues on this Tongshankou Chalcocite. This discovery from 2013 was big news in the mineral world, the Chalcocites were unbelievable, unlike any found before. The supply has long ago dried up and these have become scarce and very desirable. This is an excellent, colorful example in perfect condition. Chalcocite is a fairly common, important Copper ore but almost never seen as anything but massive deposits. Good crystals are rare and much prized and these rounded tree-like growths are really only known from this one very unusual find. Choice.

An especially attractive specimen from the now famed finds at Hubai. Fine patina and form with the treelike structure perched on crude Chalcocite crystal base. These have been found in many forms in this find but this habit is especially nice and quite rare.
