Do gemstones/healing crystals really work, and if so then HOW and WHY?
I don’t know with any significant degree of certainty.
I strongly suspect that in as much as they work, they work because people believe they work.
The power of belief is extremely strong.
We are very complex entities, and our brains are capable of influencing most of our body’s chemistry.
And having said that, I do carry a crystal Laurie sent me when I was diagnosed terminal cancer. If nothing else, it reminds me that someone on the far side of the planet, whom I’ve never physically met, cared enough about me to to send something to the other side of the planet. And that feeling of being appreciated and valued is amazingly powerful.
