Healing gemstones are believed to have therapeutic properties that promote physical, emotional, and spiritual well-being. They are used in practices such as crystal healing, meditation, and chakra balancing to harness their energy and enhance the healing process. Some of the most popular healing gemstones include amethyst, rose quartz, black tourmaline, and citrine. It is important to note that while gemstones can be a helpful tool for self-care, they should not be used as a substitute for professional medical treatment.
