Crystal healing is a form of alternative healing, using crystals and gemstones. The idea behind it is that crystals are often said to help stimulate the healing process. As healing can be as much emotional as it is physical, this form of treatment has been used for headaches, insomnia and cancer.

The crystals are said to contain energy that can be transferred to restore health and fight against disease, as well as offer spiritual guidance. The argument some supporters of crystal healing make is that, whilst the stones do not cure disease directly, they can help to correct the underlying problems. Each healer has their own opinion, and some use the method in conjunction with other methods.

The main promise behind the need for crystal healing, is that illness occurs when there is an imbalance between a person and divine energy. This divine energy, or light, is believed by some healers to be the very foundation of universal creation. The crystals are said to help correct this imbalance between us and our universe.

The gemstones are applied to certain energy centers, known as chakras. They are said to draw light and color to the aura of the body, creating a flow of energy. This flow is often thought to promote a sense of healing through the re-balancing of the body's energy.

Some of the better crystal therapists have been thought to have an instinct which can detect the exact location in the body where the energy is being blocked. That means they can place the crystals on the parts of the body that will promote healing most effectively. The stones are of varying sizes and colors and each promote a distinct healing quality.

Sapphires have been said to aid mental clarity, whereas amethyst stones are thought to promote a calm mind. Rubies have been said to help promote courage, as well as clean the blood. The crystals are all chosen depending on the individual's needs. It is not unknown for some to carry the crystals in their pockets, and for some to put them on chains, in the bath with the water, as well as put them around the home.

Crystal healing can be traced back to ancient times when Greeks and Indians thought gemstones provided light to another world. Some cultures were of the opinion that spirits lived inside the crystals. Their use as a form of alternative therapy for a variety of diseases is well-known.
