"A must-read for crystal lovers of all levels of expertise. Each page is packed with helpful tips, crystal recommendations, and concise tables. The photographs and diagrams are both inspiring and beautiful, as they will encourage readers to put these tools to use in their own lives. This book is perhaps the most informative on the subject, and it is sure to be the definitive work on crystal grids for years to come."  - Nicholas Pearson, author of Crystal Healing for the Heart and Crystals for Karmic Healing
