I recently purchased this book for crystal identification while in client sessions and have found this too be the perfect one. Every crystal I own or have heard of is listed in this book! Half a page to a full page of fully coloured specs on each stone as well as multiple pictures of each; Properties, history, traits, chakra and benefits and well as stone purposes and meanings ... it has everything . For this price it's a must add to any collection.
