Philip Permutt discovered crystals around fifteen years ago after a severe illness; he has been practising as a crystal healer and teacher ever since. He owns and runs iSiS Crystals, the largest and most successful crystal store in the UK, with its integral healing centre. Philip is also a dowser and uses this ability, together with the magic of crystals, to change the energies in homes, offices and shops. 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, both available from CICO Books.
