This book is loaded with a lot of great information and is the perfect quick reference to over 200 different crystals. There is plenty of information about the spiritual and physical impacts of crystals on the body is in there as well. 
I turn to this book a lot when I'm after a more indept explanation of a crystal. 

It covers the practical and esoteric properties of each stone, including spiritual, mental, psychological, emotional and physical effects, plus its use in crystal healing.
