Crystal Cleansing is a practice within the realm of alternative therapy and spiritual healing, where crystals and gemstones are purified of accumulated negative or stagnant energies. 

This purification process is essential for maintaining the crystals' efficacy and ensuring they can fully harness their inherent healing properties. Practitioners believe that by cleansing crystals, one can restore their natural vibrations and optimize their ability to promote physical, emotional, and spiritual well-being. Various methods are employed for cleansing, including exposure to moonlight, smudging with sage, immersing in saltwater, and using sound vibrations from instruments like singing bowls. 

Each method is chosen based on the type of crystal and the specific intention behind its use. Regular cleansing is recommended to maintain the potency of the crystals, especially after they have been used in healing sessions or have been exposed to intense negative energies. This practice not only revitalizes the crystals but also helps to enhance the overall energy of the space where they are kept, contributing to a more harmonious and balanced environment.
