This is one of those questions that is difficult to put into my own words. It’s one thing to experience the healing power of crystals and stones (which I have), another thing to explain them.
So I’m going to cheat and give you a link to an article from a person who can explain it way better than I ever could.
Not only is she a crystal expert that backs the information she provides with science & metaphysics combined but she’s been offering online courses and certification in crystal healing for some time now.
So please read Hibiscus Moon’s blog post on How & Why Crystals Have Healing Properties
I didn’t know why & how crystals worked when I started buying them around 7 years ago. All I knew was for whatever reason, I was drawn to them. I can look back on it now and understand that I was drawn to them because I had some healing to do.
There is still so much to learn about this amazing universe we live in but I definitely have a better understanding of how crystals and stones can heal.
