Clarus Products use Sympathetic Resonance Technology (SRT), a proprietary system based on years of research. The devices act like a tuning fork, resonating with your biological energy to boost energy and fight stress caused by EMFs. The Q-Link combines an attractive piece of jewelry with the Clarus technology. It contains a crystalline cell that acts as a resonator with your biofield; a tuning board; and a copper coil that functions as an antenna. 14-karat polished gold pendant has copper coil on the back. Comes on 24" gold-filled snake chain. Choice of brushed (shown above) or polished finish (click here for photo). Click here for a study on Q-Links and EMFs.
