A stone can pass onto others any energy that it has stored within it. Periodically, stones need to be cleansed of any unwanted energies that they may have collected from you, from others, or from the environment.
Bracelets should be cleansed and recharged after they are purchased and regularly after they are worn. Your bracelet may be cleansed by passing them through the smoke of a white sage stick several times or by rinsing it under cool running water. You can recharge your bracelets energy by placing it out in direct sunlight for a few hours.
