books about crystal healing

Hi...I'm new to this topic but what to learn more about it and how to apply crystals for healing and how to work with them...
Is there a good book for a beginner anyone could recommend?
thanks in advance

My personal favorite is Diane Stein's Healing With Gemstones and Crystals. I think my edition is older than the ones I was able to find on Amazon, as the cover of my book is blue with a different image on it.

But the information is extremely clear and concise, and it's an excellent reference for the use of gemstones in healing.

I have the Encyclopedia of Crystals by Judy Hall and love it. It has nice big color photos and a description of each.

Thank you both for your replies! Will definitely look them up :)
