Query: Healing Power of Gemstones

It wasn't what I was expecting or what I wanted. I just skimmed through the first 80% of the book which to me was superfluous information. I just wanted to know about how to apply the healing power of gemstones. For me it just wasn't there. I wanted what gem should be worn where to accomplish certain goals but that was not covered. I would not recommend this book for anyone looking for that information.
