Nfp Grounding uses a proprietary process of embedding the 7.83 Hz natural earth frequency into our jewelry. Enjoy the benefits of 7.83 Hz, including pain reduction, headache relief, and much more. Each piece of Natural Frequency Product jewelry is embedded with the Earth’s resonance of 7.83 hz. This process will create a sympathetic resonance vibration between the jewelry and the individual wearing the product. When our jewelry touches the body, it reunites your body to the natural frequency of 7.83 hz, and will aid in the healing process of restoring the connection to your own natural energy.
