I would love to share some books with you. My very favorite applications book is HEALING WITH CRYSTALS & CHAKRA ENERGIES, by: Sue and Simon Lilly. It's done wonderfully and is very easy to use.

Another reference book I use often is, THE ILLUSTRATED GUIDE TO CRYSTALS, by: Judy Hall.
Next up, the book I found most of the information for my healing stones attribute page, (it's a really wonderful reference book with very detailed pictures) HEALING CRYSTALS AND GEMSTONES, by: Dr. Flora Peschek-BOhmer Gisela Schreiber.  Last but not least,(another practical use book) A HANDBOOK OF CHAKRA HEALING, by: Kalashatra Govinda.
