I just started to learn about gemstones for use with the chakras, and healing, etc. This book was recommended to me and I'm glad it was.
The books contains excellent information on some stones and metals. Very practical also. It's not "The Complete Guide to Stone Power" due to it's limited amount of listed stones. But with the ones that are being explained the author did a great job. Great for beginners, or the very busy business person interested.
