Judy Hall (Wikipedia)

This is Wikipedia's article on Judy Hall, the British author known for her extensive writing on crystal healing and karmic astrology, recording her education and her long publishing career within contemporary crystal and esoteric practice. Its strength is that Wikipedia articles on figures with a substantial public bibliography are generally reliable for standard biographical facts of this kind, career milestones and publication history. Its limit is structural: it is a perpetually community-edited reference rather than a peer reviewed publication, so it is the right source for biographical detail about Hall herself but not for any claim about crystal healing's own claimed therapeutic mechanism, which has no independent scientific support and needs a source addressing that question directly rather than a biography of one of its prolific authors.
