This is a staple!
I was on the fence about buying this book because I didn’t know whether it would be to simple or very in depth/hard to understand. I am so glad I purchased it because it’s right in the middle. I am a beginner with crystals and found it easy to understand and very informative. I read the whole book in the first several days of receiving it. A nice guide to have on hand. I do wish it had some additional crystal info since some of the crystals sold on this site are not in the book but overall a great purchase. I wouldn’t hesitate to buy it again.
