Plancheite is a rare secondary, hydrated, copper silicate. A fine vug on gossan matrix has powder-blue plancheite covered by and highlighted by a multitude of thin, water-clear Baryte blades and further accented by plancheite-included calcite crystals and a couple of quartz crystals. For the locale, this is a very highly representative combination specimen featuring this rare copper silicate.
