Amethist has been used for centuries to help with pain but so has amber. I don't trust a lot of things that are so gimicky. I have been thinking of getting an amethyst and amber bracelet to help with pain. I would try that before spending almost $9000 for a heating pad. I have a heating pad that works well. I mean if you want a heating pad you can adjust the temp on go get a reptimat and rheostat lol. Oh wait thats for my python. You could honestly put a rheostat or temp control on a good heating pad and probably get the sam effect.
