A very informative and inspiring book in regards to crystals and stones. I own many books on crystals and I have to say that this is my favorite. Many stones shown and described in this book are not in any of the other books I own. I would most definitely recomend this book to others. Besides giving a description of the stone and it's properties, this books delves into the spirituality and energy in which each stone carries. Another great aspect of this book is the fact that it was written by two authors so you'll read and understand the interpretation of two minds. This is a wonderful book. I have enjoyed it very much so.
