Crystals by Jennie Harding
This is my go-to reference book for healing crystals. It is organized by color, so you can quickly flip through to see about options for jewelry, and it also has a detailed index in the back. If you need information about a specific ailment, there is a chart in the back that tells you everything you need to know. This book is the only one I use when I’m at shows, because I can get the info I need quickly.
