These claims are unsubstantiated and have not been proven scientifically. The effectiveness claimed is not feasible either biologically, nor medically and physically. Amethyst is not able to emit light, warmth, or negative ions without any external energy source. If it was in fact to emit such radiation, this would be radio-active and probably hazardous to human health. Some of these products contain an electrical heat source. | These claims are unsubstantiated and have not been proven scientifically.
