It works, but HOW?!: Everything is energy and emits an energy frequency. Frequencies can be beneficial to the human body and many are harmful, such as the EMF (electromagnetic field) that most of us are bombarded with 24/7 from cell phones, video games, computers, artificial lighting, etc. This constant insult keeps us from a biological harmonious state. When Tuning Element jewelry comes in contact with skin, the Hertz frequency embedded in the metal (just like a tuning fork- which never goes out of tune) resonates with the body and allows optimal function while providing protection.
