Philip Permutt discovered crystals 15 or so years ago after a severe illness and has been practicing as a crystal healer and teacher ever since. He owns and run iSiS Crystals, the largest and most successful crystal shop in the UK, and its integral healing center. Philip is also a dowser and uses this ability, together with the magic of crystals, to change the energies in homes, offices, and stores. Philip has lectured on crystals and crystal healing, and runs workshops on crystals and associated subjects. He is the author of The Crystal Healer, which has sold over 50,000 copies worldwide, and The Little Book of Crystal Tips and Cures, which has sold over 55,000 copies, both available from CICO Books.
