These come from a remote copper mine, and only out of old collections now. This is one of the few larger examples of this old classic Aussie material I have seen on the market, and features a nice ridge of sharp crystals perched on contrasting matrix. The crystals are to just over an inch and are actually a rare double pseudomorph! The chrysocolla has replaced malachite, which itself replaced the original azurites. Small gem orange wulfenites add decoration, a classic association for the locale. Overall, then, this is both big and unusually fine for its aesthetics. I was told that most of these came out prior to the 1970s, and Frank obtained it in trade at Tucson one year. He loved it because of the similarity to the pseudomorphs of his Arizona locales.
