A white chalky Kaolinite replacement of a large and perfect set of Orthoclase Carlsbad twin. Unfortunately it has been repaired, there's a bread right through it that has been carfully glued back together. There's also a place that where someone apparently chisled into it, we're not sure why. Although it's not the best quality, it's a great example of both a pseudomorph & a Carlsbad twin.
