Larimar is a soft stone that doesn’t need to be soaked in water for a longer time, so you can rinse them in the running water and smudge them in the smoke or the salt to restore their power. And for charging your larimar ring, you can put them in the light or under the full moon and let them soak the light and energies of the moon. In this way, you can bring back the charge of the stone and get back its potency.
