Cleansing: Citrine has a reputation for not absorbing negative energies, but regular maintenance is recommended. To cleanse it gently, you can use fumigation (sage or palo santo) or briefly place it under a stream of clear water, avoiding prolonged immersion.
Recharging: To restore its brilliance and positive energy, expose your Citrine to natural sunlight for a few hours (ideally morning sun, which is less intense) or to moonlight. You can also place it on a cluster of rock crystal or in an amethyst geode, which will allow it to regain its full vibrational strength.
