Crystals

Materials that have their molecules arranged in a specific, highly ordered internal pattern. This pattern is reflected in the crystal's external structure that typically has symmetrical surfaces.

Many common substances, such as salt, sugar, diamonds and quartz, form crystals. They can be shaped so that they will vibrate at a specific frequency and are widely used in radio communications and computing devices.

Many New Agers, Wiccans, and other Neopagans and others believe that crystals possess healing energy.
