Gunheath China Clay Pit, Stenalees, Hensbarrow Downs, Luxulyan Area (Luxulian Area), St Austell District, Cornwall, England, UK

Plancheite supposedly collected here in 1958 by Arthur Kinsbury (1906-68) is now considered "very doubtful" and probably from Arizona. This is one of a number of likely or definitely falsified Kingsbury localities.
