Description

You are looking on a superfine and classic combination piece of deep green Chrysocolla, amber Wulfenite and white botryoidal Calcite. 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 well developed crystals perched on contrasting matrix. The crystals are to just over 3,5 cm and are  actually a rare double pseudomorph! The chrysocolla has replaced malachite, which itself replaced the original azurites. Small gem amber 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.
