Pendant 42 * 42mm, thickness 6mmNatural volcanic health stone pendant Negative ion energy stone pendant contains more than 70 rare trace elements such as natural activated carbon, potassium, strontium, zinc, etc. It is made by high temperature burning, and releases the universe's natural energy at a high-speed seismic frequency of 299000kc / sec. And constantly release a lot of negative ions and infrared rays, and contain huge energy. Its wavelength is completely consistent with the body wave at room temperature , and its penetration ability is as high as 13-15 cm under the skin. 1) It can promote blood circulation, accelerate metabolism, and eliminate pathogens on cell membranes in the body. 2) Form a protective wall with harmful external magnetic waves to reduce the harm to the human body. 3) Promote blood oxygen supply in the body. 4) Eliminate blood dirt such as fat and protein particles, and promote blood circulation. 5) Promote effective detoxification of cells in the body. 6) By continuously supplementing the source of cells in the body and adjusting its frequency, it can effectively prevent disease invasion. 7) It can release a large amount of negative ion energy of 1500-2000 pieces / piece, gathering health care functions and decoration functions.Special link for my dear friend Eko -- quantum PendantNow, you can achieve better health and greater vitality, by improving body's circulation, neutralizing negative energies, and re-charging your body's energy field with the right energy frequencies with Quantum Pendant.Made in China, using advanced nanotechnology know-how, with natural minerals structurally bonded together, Quantum Pendant restores balance and harmony to the body.
