I was given this as a Christmas present one year as the person who gave it to me knew that I love crystals as it was my favourite part from stuying geology for a while and did have some belief in their uses.
I really enjoy this book and my copy is rather well worn now and is often found close at hand. I like how the crystals are listed from A to Z and the photos are lovely. It has been a very useful companion in my own work with crystals and I have recently purchased the second volume as I have picked up some unusual and new crystals I am not terribly familiar with. I highly recommend this book for anybody curious about the use of crystals be it for healing, aiding you on you spiritual path or enhancing your daily life even if it is just by placing an attractive crystal in your room to brighten it up.
However in answer to one of the negative reviews, I do think anybody relying on crystals to cure sickness alone is being very foolish and it states this in its caution message at the begining of the book. However there is nothing wrong with selecting a crystal to help out when one is ill.
