In order to tap into the healing power of amethyst crystals, it’s key to regularly cleanse them as they do store and hold energy from their surroundings. Water, sound, and smoke can all cleanse crystals of stagnant energy. To cleanse them with water, you can simply run the amethyst under the faucet or bathe them in a bowl. To smudge your amethyst, light your preferred bundle of herbs or a smudge stick and let the smoke clear the crystals. Sound baths use healing frequency and are effective in cleansing crystals of old energy also (via Tiny Rituals). Some crystals have the power to clear the energy of other crystals, like selenite and quartz, so simply placing your amethyst in the presence of one of these will help you tap into its healing powers.
Saltwater, sunlight, and moonlight are other surefire ways to cleanse your amethyst. This one may come as a surprise, but if it works for a broken iPhone, it very well may work for a crystal in need of cleansing: brown rice. You likely know the trick -– place your iPhone (or amethyst crystal) in a bowl of brown rice for 24 hours (via Healthline).
