What a beautiful way to help decrease the amount of harmful EMF waves that our bodies are exposed to on a daily basis. And, it doubles as a natural air freshener. My brother, Michael, gave me one for my birthday. I love it. I did read somewhere ( can’t remember where) that’s it’s best to put it on top of something to avoid heat stains to your furniture. The crystal does get hot over time  but, I’ve always had it in a glass dish.
