There are many crystal books out there and like most people I have my favorites. Here are some Crystal Healing book that I recommend: 

Great for Beginners: 

1. The Crystal Bible: Volume 1 by Judy Hall 

2. Crystal Healing by Judy Hall

3. The Book of Stones, Revised Edition: Who They Are and What They Teach by Robert Simmons and Naisha Ahsian 

Other Books that I love and have in my collection: 

1. The Pocket Book of Stones, Revised Edition: Who They Are and What They Teach by Robert Simmons (small - fits in a purse which is great when you are going to a store to look for crystals) 

2. Encyclopedia of Crystals, Revised and Expanded by Judy Hall 

3. Love is in the Earth: A Kaleidoscope of Crystals - The Reference Book Describing the Metaphysical Properties of the Mineral Kingdom by Melody 

4. Love Is in the Earth - the Crystal and Mineral Encyclopedia - the LIITE Fantastic and the Last Testament: The Encyclopedia Describing the Metaphysical and Mineralogical Properties of the Mineral Kingdom by Melody - (this is a very large book that I would suggest as a reference tool - however there are no pictures of the stones)

There are many others but these are a few of my top favorites
