Herkimer diamonds are from Herkimer NY, so naturally fair trade. Mine are from a man who personally mines his own claim, so I know their authenticity. Herkimer diamonds gently release and transform, bringing your souls purpose to the fore and activating the light body. These bracelets wrap twice and tie (on a small wrist they can wrap three times). I made them super long so you can adjust and cut off the ends to customize your bracelet.
